The Perfect Crown Review – A Royal Romance That Lost Its Way

Our story begins with a narrator explaining that the royal family’s history dates all the way back to the Joseon Era. We then meet our female lead, Seong Hui Ju, who has taken over one of her father’s companies, Castle Beauty. With the Crown Prince’s birthday celebration approaching, she plans to attend the royal event and use the publicity to boost her company’s sales. Around the same time, we’re introduced to our male lead, Grand Prince Yi An, along with his loyal right-hand man, Choi Hyun.

That evening, the birthday banquet gets underway with guests arriving in elegant but fairly modest outfits. Hui Ju, however, makes sure all eyes are on her by showing up in a red suit that’s considered inappropriate for the occasion. Inside the palace, she reunites with her older brother, Tae Joo, and the two immediately fall into bickering. The guests are then invited into the dining hall where Yi An makes an entrance fashionably late, still dressed in his hunting clothes. Queen Mother Yi Rang is far from amused and wastes no time publicly scolding him for his lack of respect.

After dinner, Hui Ju runs into her close friend, Prime Minister Jeong Woo, and the two spend a few moments catching up. Not long after, Yi An catches Hui Ju wandering through a section of the palace that’s off-limits to guests. But before either of them can go, a loud explosion echoes through the palace grounds. They rush toward the commotion and discover that a fire has broken out. The sight immediately triggers Yi An’s PTSD since the king died in a palace fire three years earlier. The tension eases slightly when the eight-year-old Crown Prince, Yi Yun, is found safe, while Jeong Woo quickly takes control of the situation by ordering his staff to investigate the fire and manage the inevitable media frenzy. After things calm down, Hui Ju decides to leave the palace early and heads home with her secretary, Do Hye Jung. 

The following day, Queen Mother Yi Rang meets with Yi An to explain that she’s worried his role as regent is beginning to overshadow the Crown Prince. To prove his loyalty to the royal family, Yi Rang insists that Yi An marry a woman of her choosing. Meanwhile, the marriage issue spills into Hui Ju’s own life. After discovering that her father has started searching for a husband on her behalf, she storms over to his house, furious. She tears into both her older brother and his wife for helping organise the list of potential suitors and is even more offended that every candidate is beneath her socially and professionally. They remind her that she’s still the illegitimate daughter of the family and shouldn’t expect much better. 

Back at Castle Group, Hui Ju decides that if she’s going to get married, she’ll do it on her own terms. Rather than settling for one of her father’s handpicked candidates, she concludes that the only marriage worthy of her is one into the royal family itself. Naturally, she sets her sights on Grand Prince Yi An and submits a formal request for a royal audience. At the same time, the public continues debating Yi An’s decision to wear a cheolik to the birthday banquet, leaving him in no mood to meet with anyone. He refuses every audience request that comes his way—including Hui Ju’s.

That decision only motivates Hui Ju even more. Eventually, she reminds him that she’s his junior from Seonggyungwan, and that small connection is enough for him to finally agree to see her. The meeting itself is surprisingly short. Hui Ju calmly asks him to marry her, Yi An immediately says no, and just like that the audience is over. Rather than taking the rejection personally, Hui Ju sees it as the beginning of a challenge.

Later, Yi Rang reflects on the day the king died. We learn that before the fire broke out, the king had planned to abdicate the throne and hand it over to Yi An. Furious at the idea, Yi Rang burned the royal decree bearing the king’s seal and declared that she’d rather see him dead than let Yi An become king. Moments later, the palace fire began, claiming the king’s life before the announcement could ever be made.

Some time later, the annual Economic Honours of Korea ceremony arrives where Hui Ju receives one of the evening’s awards. After sharing her award online, Hui Ju settles in for a staycation at the hotel hosting the event. Jeong Woo invites her to dinner to celebrate, and it’s becoming increasingly obvious that his feelings for her go well beyond friendship. 

Meanwhile, Yi An’s health begins acting up again, forcing him to stay at the same hotel. Refusing to make a scene by going to the hospital, he sends Choi Hyun out to collect medicine and food instead. On his way back, Choi Hyun unexpectedly runs into Hui Ju, who immediately calls in her private doctor. 

The next morning, news of the hotel incident reaches the media and speculation immediately runs wild. Reporters begin claiming that Hui Ju is secretly dating Grand Prince Yi An. Rather than panicking, Hui Ju sees the entire scandal as free publicity and immediately starts planning how to use it to Castle Beauty’s advantage. That evening, Yi An invites Hui Ju to his private residence to apologise for dragging her into the scandal. He asks what she wants in return, and Hui Ju doesn’t hesitate for a second. She tells him she wants marriage. After giving it some thought, Yi An agrees to the arrangement but warns her that becoming part of the royal family will come with relentless public scrutiny. Hui Ju accepts the risk without a second thought.

Not long afterwards, the pair step out in front of a swarm of reporters hand in hand, officially confirming their relationship. The following morning, Jeong Woo soon visits Hui Ju at her office, where she continues selling the image of a woman hopelessly in love with Yi An and eager to become his wife. Before he leaves, she asks him for a favour. We later see Jeong Woo seeking advice from a priest as he struggles with the conflict between helping Hui Ju achieve her goals and dealing with the feelings he’s secretly held for her all these years. 

At the same time, Hui Ju’s phone conversation with Yi An is abruptly interrupted when four teenage girls ambush her in her home parking lot and pelt her with eggs. She handles the humiliating situation surprisingly well before heading upstairs, where her father is waiting. Rather than showing concern, he accuses her of staging the romance for attention and cruelly blames her not only for his wife’s death but also for being greedy despite being his illegitimate daughter. It’s a brutal confrontation, and Yi An immediately notices something is wrong when he calls her later that evening. The next thing we know, he’s standing outside her door carrying Subway sandwiches.

As they eat together, Hui Ju opens up about being attacked and the painful argument with her father. Yi An doesn’t waste any time deciding what to do. That very night, he moves her into his private residence. Once they’re settled in, he finally explains why he agreed to the marriage. He believes Hui Ju is the only person who would truly understand if he ever chose to pursue the throne himself.

Time passes and Hui Ju begins royal etiquette lessons under the guidance of a court lady as part of her preparation for becoming a member of the royal family. During her phone call to Yi An, she casually mentions that her red sports car is in the repair shop after someone crashed into it. Elsewhere, Tae Joo and his wife realise Hui Ju marrying into the royal family could actually work in their favour. Since members of the royal family aren’t allowed to participate in business, Castle Beauty would eventually be left without Hui Ju, opening the door for Tae Joo to take over the company.

A few days later, Jeong Woo brings Crown Prince Yi Yun to Yi An’s residence and finds Hui Ju completely overwhelmed by her endless royal lessons. More than happy to escape studying, she greets the young king and convinces everyone to play games instead. After winning, Yi Yun excitedly claims his prize—a ride in Hui Ju’s famous red sports car. Everyone reluctantly agrees, provided Jeong Woo and several royal security vehicles follow closely behind. At first, everything goes smoothly until Hui Ju suddenly discovers the brakes have failed. The car begins accelerating uncontrollably as she desperately swerves around traffic while Yi Yun panics beside her. Just when disaster seems unavoidable, another vehicle pulls directly into their path and absorbs the full impact. The driver climbs out of the wreckage, and of course, it’s Yi An.

News of the accident quickly reaches the palace, sending Queen Mother Yi Rang rushing to the hospital. Thankfully, Yi Yun escapes with only a few bruises, but Yi An is taken straight into surgery with a serious shoulder injury while Hui Ju remains unconscious. Fortunately, Yi An’s surgery is successful and doctors expect him to make a full recovery. Yi Yun later visits Hui Ju, who reassures the guilt-ridden boy that none of what happened was his fault. 

As soon as she learns Yi An is awake, she rushes to see him, and the two spend their time teasing and flirting with one another. By this point, Yi An’s feelings are becoming increasingly obvious, even if he hasn’t admitted them out loud yet. Back in her hospital room, Hye Jung vents about how every disaster in Hui Ju’s life lately seems to have started the moment Yi An entered it. She questions why Hui Ju is still going through with a marriage that’s supposed to end in divorce after just three years anyway. Unfortunately for Hui Ju, Jeong Woo overhears the entire conversation, forcing her to finally admit that the marriage has always been a business arrangement. Seeing an opportunity, Jeong Woo immediately asks Hui Ju to marry him instead, arguing that he also has status and can give her everything she’s looking for. Before we get to hear her answer, the story cuts away to Hui Ju discovering that Yi An has already been discharged from the hospital without saying goodbye. After repeatedly ignoring her phone calls, his sudden distance leaves her completely confused. Hye Jung then casually mentions that Yi An had been standing outside Hui Ju’s room while Jeong Woo was inside. Realising he may have overheard the proposal, Hui Ju immediately rushes to Yi An’s house.

Upon arriving, Hui Ju is informed by Yi An’s staff that she’s no longer welcome at his house. After collecting her belongings, she quietly heads home. That night, we learn that Hui Ju turned down Jeong Woo’s proposal because his status is only temporary, while royal status lasts for life. Unfortunately, Yi An overhears this and is left believing she still only wants him for his title. Hurt by what he heard, he continues to ignore her.

Yi An officially calls off the engagement but lets Hui Ju know that someone tampered with her car and promises to find whoever was responsible. Hui Ju isn’t about to sit back and wait, so she has Hye Jung investigate the mechanic who worked on it. Meanwhile, Yi An strikes a deal with Yi Rang and manages to get Hui Ju invited to the highly exclusive Inner Court Banquet. Ironically, despite wanting an invitation for so long, Hui Ju rejects it. 

The two eventually meet face to face, where Hui Ju calls Yi An a coward and tells him he should stop bending to the will of the people trying to control him. Around the same time, Castle Beauty’s staff discover that the mechanic who sabotaged Hui Ju’s car used a Castle Group credit card—one managed by Tae Joo. He agrees to help investigate while Hui Ju finally accepts Yi An’s invitation to the banquet.The night before the banquet, Yi An asks her to teach him how to lead instead. Hui Ju simply tells him to stay by her side and she’ll show him. 

The day of the banquet arrives and Hui Ju is fashionably late. Elsewhere, Tae Joo finally uncovers the identity of the man who tampered with Hui Ju’s car, only to discover he conveniently died the day before. As Yi Rang leads the procession through the gardens with all the noblewomen following behind, Hui Ju quietly walks at the very back as expected. Then, without warning, Yi An shows up, walks straight over to Hui Ju, and asks her to show him how to lead. She takes his hand, and together they walk past every noblewoman and straight past Yi Rang herself.

Some time later, everyone gathers for the banquet’s after-party. Yi Rang is in unusually high spirits, convinced Yi An still intends to honour their agreement and end things with Hui Ju. After all, she’d only invited Hui Ju because Yi An had supposedly broken off the engagement. Instead, Yi An and Hui Ju make a grand entrance, share a dance in front of the guests, and completely shatter her expectations. When the dance ends, Yi An gets down on one knee and proposes using his late mother’s ring. Hui Ju happily accepts, leaving both Yi Rang and Jeong Woo completely stunned. To make matters even worse for Yi Rang, Yi An asks the young king to bless their engagement. Ignoring his mother’s desperate attempts to stop him, Yi Yun gives the royal blessing, sending the media into an absolute frenzy. Heartbroken as he is, Jeong Woo still chooses duty over his feelings and refuses to overrule the king’s decision.

Yi Rang and Yi An share a dance, but it quickly turns into a confrontation. This time, however, Yi An is ready for her. He brings up the night she burned his brother’s royal decree, immediately throwing Yi Rang off balance. For everyone else, though, the evening is a complete success. Even Tae Joo is thrilled—but only because Hui Ju’s marriage means she’ll eventually have to step away from the company. Elsewhere, Hui Ju officially moves back into Yi An’s residence.

Not long after, Hui Ju and Jeong Woo arrive at the palace together, immediately irritating Yi An. He quietly warns Jeong Woo to be more mindful of how he behaves around Hui Ju. Jeong Woo, however, casually admits that he already knows their marriage is nothing more than an arrangement. Yi An is clearly bothered by this so when Hui Ju brings up drafting a marriage contract, Yi An simply challenges her to go ahead and write one.

That evening, the couple is invited to dinner with Yi Rang. Unsurprisingly, the meal quickly turns sour as Yi Rang tears into Yi An without holding back. To wash away the miserable evening, she takes Yi An out on her yacht. One quiet moment leads to another, and before long, the two end up making out on the deck.

The next morning is wonderfully awkward as neither of them can stop thinking about what happened. Back at Castle Beauty, Hui Ju reluctantly agrees to transfer her shares to Tae Joo, secretly hoping he’ll prove he’s incapable of running the company without her. Meanwhile, the young king officially chooses July as the date for their wedding. 

That night, Yi An hides the marriage contract away inside a secret cabinet before pulling out the burned royal decree stating that the late king wanted him to inherit the throne. Elsewhere, Sung Won reflects on the night of the fire, and we’re finally given a much clearer picture of what happened. He found Yi Rang curled up on the floor after she’d learned the king planned to abdicate in Yi An’s favour. When he asked what she’d done, she calmly replied that she burned it all to the ground. Umm… what??

At last, the wedding day arrives, and everyone is understandably excited. Thankfully, the wedding itself goes off without too many issues, aside from Hui Ju tripping near the beginning. The ceremony continues, the royal rituals are completed, and the newlyweds receive everyone’s blessings before returning to the palace to be officially welcomed. Everything seems to be going perfectly… until Hui Ju suddenly becomes dizzy, her vision blurs, and she collapses in front of the entire nation watching the live broadcast.

Yi An immediately takes charge and rushes Hui Ju to Castle Hospital. The doctors soon discover she has digoxin toxicity and reveal that she only survived because she doesn’t regularly take the medication. Jeong Woo completely loses his composure and lashes out at Yi An, while Yi An fires back by demanding a full investigation into everyone present at the palace. Jeong Woo wastes no time launching the investigation, personally interviewing everyone who had access to the wedding banquet. Meanwhile, Hui Ju finally wakes up in hospital. The moment Yi An hears the news, he completely forgets royal etiquette, breaks the palace’s no-running rule, and sprints through the hospital to see her. The second he reaches her room, he wraps her in a hug and breaks down in tears.

Yi An is later questioned himself and reveals that he believes he—not Hui Ju—was the intended victim. He occasionally takes digoxin as medication, meaning that had he drunk from that cup instead, the poisoning almost certainly would’ve killed him. Hui Ju pieces together the rest, realising that when she stumbled during the ceremony, she accidentally knocked the drinks, causing their cups to be switched. Hui Ju is eventually discharged from the hospital, but not before putting on an extra convincing performance for the cameras. Once the media leaves satisfied, she heads to the palace, where she officially begins living as part of the royal family. Not long after, Jeong Woo confirms Hui Ju’s suspicion that the poisoned goblet was indeed how she was poisoned. As he’s piecing everything together, a nervous maid quietly steps into his office.

The following morning, there’s a bit of a staff shuffle. Choi Hyun becomes Hui Ju’s official aide, while Hye Jung takes over as Yi An’s. The royal staff immediately begin preparing the newlyweds for their first official public appearance, which takes place at their former high school. Everything starts off smoothly enough. Hui Ju delivers her speech first, but halfway through, the audience suddenly becomes distracted. Phones start coming out, whispers spread across the room, and the atmosphere shifts almost instantly. The media has discovered the existence of their marriage contract. Within moments, reporters storm the venue, everyone is talking over one another, and the entire event falls apart. With reporters swarming the building, Yi An and Hui Ju slip out and make their way to Jeong Woo’s office. Public opinion immediately spirals out of control as rumours and criticism flood every news outlet. 

The next day, protests are in full swing. With pressure mounting from every direction, Jeong Woo tells Yi An to shoulder the blame alone by asking Yi An to step down as regent altogether. Before we hear Yi An’s response, the story jumps back five days to the moment the frightened maid entered Jeong Woo’s office. She confesses that she was the one who placed the medication into the goblet but insists she never knew it was intended to kill anyone. Desperate to pay for her brother’s surgery, she’d accepted money from Sung Won and had been working for him ever since.

Jeong Woo immediately confronts Yi Rang with the truth. To his surprise, she appears genuinely shocked by what her father has done. When she confronts Sung Won, he doesn’t deny a single accusation. As far as he’s concerned, Yi An still has to die. Desperate to save her son, Yi Rang strikes a dangerous deal with Jeong Woo. She promises to protect Hui Ju in exchange for helping bring Yi An down. Her plan is to leak the marriage contract and turn Yi An into the centre of the scandal, effectively sacrificing him to save the monarchy. 

Back in the present, Yi An calmly refuses Jeong Woo’s request to step down, insisting he has no intention of abandoning either the crown or his responsibilities. We’re then given another flashback to the night the king died. It turns out Yi An had gone to play with his young nephew in the room next to the king’s chambers and accidentally overheard the entire conversation about the abdication decree before the fire broke out. Back in the present, a day passes and Hui Ju finally admits that her feelings for the prince have become real. Running out of options, she then goes to her father’s house, kneels before him, and begs for his help.

Later that night, while fighting back tears Hui Ju hugs Yi An before asking him for a divorce. Knowing exactly where it’ll hurt the most, she tells him he has nothing left to offer her now. The following morning, Hui Ju attends a council meeting to formally request the divorce. That’s when Castle Group suddenly shifts the entire narrative. Even Tae Joo proves useful by claiming he was the one who drafted the marriage contract, pointing out that it was never officially notarised, and arguing that both parties would ultimately lose in the event of a divorce. Just to top it all off, he threatens legal action against the media for spreading false information.

With Hui Ju’s part of the plan complete, it’s Yi An’s turn. Without warning, members of the Royal Secretariat enter the council chamber and announce that Yi An must prepare to receive the young king’s royal decree. Turns out Yi An had a plan of his own all along. Rather than surrendering his position, he’d convinced Yi Yun to voluntarily return the throne to him. Yi Yun immediately signs the decree, leaving everyone stunned. Following royal tradition, Yi An is expected to refuse the throne three separate times before officially accepting it.

After the meeting, Yi Rang completely unravels after hearing the news. Yi An continues giving Hui Ju the cold shoulder, leaving her miserable and full of regret. Eventually, she finds him at his private residence and finally confesses that she truly loves him. One thing leads to another, and the two spend the night together.

The following morning, they return to the palace. Yi Rang privately begs Yi An to reject the throne, reminding him that she sacrificed everything to protect it. Yi An refuses. Accepting defeat, Yi Rang informs Sung Won of Yi An’s decision. Sung Won, however, refuses to lose. Later that night, Jeong Woo secretly pays him a visit.

The final day of the royal decree arrives, and the palace is thrown into chaos. Yi An prepares to formally accept the throne while Hui Ju heads off to meet Tae Joo after receiving a phone call about the company’s next steps. Soon after, Yi An receives a text from Jeong Woo asking him to stop by the council hall before heading to the throne room. Moments later, a massive explosion echoes across the palace grounds.

Hui Ju rushes toward the smoke and discovers that the council hall has erupted into flames. Hye Jung arrives and reveals that Yi An was inside the building when the explosion happened. Without hesitation, Hui Ju charges straight into the burning hall herself. She eventually finds Yi An unconscious inside, and with Choi Hyun’s help, manages to drag him to safety. Yi An survives but falls into a mild coma, while Hui Ju refuses to leave his bedside.

Later, Hye Jung points out that Yi An only went to the council hall because Jeong Woo asked him to meet there. To make matters even more suspicious, Jeong Woo seems strangely uninterested in investigating the explosion itself. Refusing to sit back any longer, Hui Ju asks Yi Rang for permission to launch her own investigation. As she continues caring for the unconscious prince, rumours of Yi An’s death begin spreading throughout the country. Jeong Woo immediately tries to take advantage of the uncertainty by pressuring Yi Rang to become the next regent. Unfortunately for him, Yi An wakes up just in time to silence the rumours himself. 

Some time later, Yi Rang finally learns the truth: it was Sung Won who ordered the gas explosion. Exhausted by years of manipulation, lies, and threats, she finally decides she’s had enough. She meets privately with Yi An, confesses everything she’s done, and hands over the evidence needed to bring her father down. The only thing she asks for in return is that Yi Yun be kept safe.

A day later, Yi Yun sends out the third and final abdication request while Yi An prepares to confront Jeong Woo. During their meeting, Jeong Woo finally gives up Sung Won and reveals everything he knows. In return, Yi An makes a shocking confession of his own: once he becomes king, he intends to abolish the monarchy entirely. With no daughter or grandson left to protect him, Sung Won is eventually arrested.

A few days later, Yi An officially ascends to the throne. As the new king of Korea, his very first order is to begin the process of ending the monarchy. Naturally, this sends everyone into a panic. Hui Ju is supportive but realistic enough to know that neither the royal family nor the cabinet will quietly accept losing centuries of power. The only thing truly on Yi An’s side is public opinion.

Time passes and Yi Rang visits her father in prison and officially cuts ties with him. As she leaves, Jeong Woo approaches and offers her a ride. During the drive, he immediately returns to making threats. He demands that she publicly oppose Yi An’s plan to abolish the monarchy and warns that if she refuses, he’ll expose her role in destroying the royal decree. Not only that, but he casually admits that he was behind the attempt on Yi An’s life and has no intention of stopping.

Hui Ju eventually turns to Yi Rang for help. To her surprise, Yi Rang reveals that she secretly recorded the entire conversation. The following day, during a royal family meeting, Hui Ju storms in and plays the recording for everyone to hear. Cornered with no way out, Jeong Woo finally meets with Yi An privately and admits the truth. He claims that everything he did was because Yi An refused to let Hui Ju go. Yi An quickly shuts that down by reminding him that Hui Ju was never his to begin with. Shortly afterward, Jeong Woo is arrested. 

With his final obstacle removed, Yi An proceeds with the public survey. The results are clear: the people vote to end the monarchy. True to his word, Yi An honours their decision. His first decree as king also becomes his last, officially abolishing the Korean monarchy and ending centuries of royal rule.

Three years later, everyone has settled into their new lives. Hui Ju returns to Castle Beauty and eventually takes over Castle Card as well after Tae Joo steps back to focus on his growing family. Even her father seems to have learned a few lessons and makes a genuine effort to support her moving forward. The drama closes on a surprisingly happy note. Yi An spends time figuring out who he is without royal duties hanging over his head and finally admits that he’s liked Hui Ju ever since their high school days. Hui Ju thrives back in the business world, while Yi Rang focuses on raising Yi Yun and encouraging him to become a musician rather than a monarch.

In the final moments, Yi An and Hui Ju attend a baseball game together. This time there are no titles, no royal expectations, and no cameras waiting for the perfect public image. So when the kiss cam lands on them, with no royal decorum holding them back, they simply kiss.

The End.
