The numbers have been impressive. The ratings have been record-breaking. But nothing tells the story of Perfect Crown‘s success quite like what happens when the cameras are still rolling and the cast doesn’t know how to stop feeling it. A brand-new behind-the-scenes video from Episode 9 is out — and it’s a masterclass in dedication.
What the Making-Of Video Reveals
The newly released making-of video begins with the actors experimenting with their portrayal, trying different enunciations to convey the gravity of the scene. IU and Byeon Woo-seok also film their hugging scenes multiple times until they perfect their movements smoothly. soompi
The emotional depth on set runs just as deep off camera. After the scene where IU gets on her knees in tears, co-star Chae Seo-an shared, “I teared up slightly,” explaining how she held her tears back for the sake of continuity. Lee Jae-won agreed, saying “My heart ached while watching through the monitor.” Chae Seo-an then revealed that IU cried for all 10 takes.
There’s warmth behind the intensity too. Despite Jo Jae-yoon’s chilling portrayal of his character on screen, he showed a softer side with the cast — complimenting Gong Seung-yeon and telling IU that he is a fan and had attended her concert.

Why This BTS Moment Matters
Ten consecutive takes in tears isn’t an accident — it’s the kind of commitment that explains why Perfect Crown hit a nationwide rating of 13.3% in its penultimate week, the highest of any show on South Korean television that Saturday. IU’s performance as Seong Hui-ju has been the emotional engine of the drama from the first episode, and this behind-the-scenes footage shows exactly how much of herself she pours into every scene.
For fans who’ve been living episode to episode, the BTS video is a reminder of what makes this drama feel different — it’s not just the fantasy setting or the chemistry, it’s the cast’s refusal to coast.
