What do you get by casting IU and Byeon Woo Seok in one drama?

Perfect Crown, the newest Disney+ K-drama, fueled immense buzz even before its premiere. Two of South Korea’s most sought-after talents captivated global audiences with their roles as Seong Hui Ju and Grand Prince I-An, a couple who are entangled in modern romance and royal intrigue.

According to director Park Joon Hwa, joining the project was an opportunity he couldn’t pass up. “I actually got on board after the two were cast. When I heard that the two were cast for the main characters, I was just very grateful,” he shared in a virtual press conference. “These two are the ones that everyone wants to work with.” The excitement extended beyond the industry — into his own home. “My daughter is a big fan of both IU and Woo Seok… she said, ‘You have to do this. You have to be part of this project.’”

Beyond its leads, he underscored the strength of the ensemble. “Not just the two, but all the cast members are just wonderful actors, and I felt very happy working together with them,” he said, later adding, “The biggest strength we can boast is our cast.” The director recalled how, during script readings, the chemistry was already palpable: “I felt like this is indeed the royal couple in front of us.”

Set in an imagined version of modern Korea under a constitutional monarchy, Perfect Crown leans heavily into immersive world-building. “The backdrop is a constitutional monarchy, but that’s not our actual reality,” Park explained. “I wanted the audience to feel like it is just like today, but there is a royal family.”

To achieve this, the production paid close attention to detail, from lifestyle to aesthetics. “I focused on imagining the physical space — how the royal family would live in a time like this. What would they wear? Where would they live? What kind of food would they eat?” he said. “I tried to bring in little details to make that convincing.” This meticulous approach extended to character design: “For the wardrobe and space, we focused on each character — where they come from, their status, and their story.”

Despite the lavish setting, Park made it a point to ground each role in relatability. “For example, the Queen Mother spends most of her time in the palace… she had to feel like the head of the palace,” he said, contrasting this with the more contemporary sensibilities of the female lead. “Hiju had to feel like someone from the modern day.” The goal, he noted, was simple but crucial: “I wanted everything to feel as convincing as possible for the viewers.”

Still, with such a high-profile cast and concept comes inevitable pressure. “I did feel a lot of pressure because so many eyeballs are on this,” Park admitted. “I’m always nervous about releasing my shows, but with this show, I really can’t wait to see how fans will react and how much they will enjoy it.” In fact, anticipation isn’t limited to audiences. “It’s actually the cast and crew who are waiting for the release… because they just can’t wait,” he added.

What sets Perfect Crown apart, according to its director, is its ability to balance distinctly Korean elements with universal themes. “There’s a lot of ‘Korean-ness’ in this drama series, obviously,” he said. “There are many universal elements that I think will resonate with anyone around the world.”

The series promises a sweeping emotional journey, one that Park believes will resonate episode after episode. “In each episode, your hearts are going to flutter for different reasons,” he teased. He even went as far as to compare its potential impact to a beloved classic: “I dare say this is a series worthy of becoming like Princess Hours.”
