IU and Byun Woo Seok’s K-Drama Trailer Faces Harsh Backlash

Byeon Woo Seok is facing backlash over his acting in the new K-Drama teaser for Perfect Crown.

The teaser dropped at the 2025 MBC Drama Awards and fans were quick to react — mostly negatively.

Byeon Woo Seok, who rose to huge fame in 2025, got slammed for his “cringy” acting. Fans say he hasn’t improved at all.

IU co-stars as Seong Hee Joo, a wealthy but commoner woman, opposite Byeon Woo Seok’s Grand Prince Ian. They enter a contract marriage in the story set in a modern constitutional monarchy South Korea.

Twitter buzz:

“The acting is so cringy.”

— Netizen

“When is the male lead going to improve his acting…”

— Netizen

“IU’s tone fits perfectly, but Byun Woo Seok only has a nice voice, no sense of authority at all…”

— Netizen

“Chemistry is so-so, but the story concept seems interesting.”

— Netizen

Some compared the vibe to Princess Hours, hinting it might find success overseas despite the critiques.

The drama’s core story follows the couple as they challenge social boundaries while trying to change their fates through marriage.

Fans say the chemistry between IU and Byeon Woo Seok is just “average” for now.

The final verdict may shift once the drama officially airs in 2026, but early impressions are far from glowing.
