Byeon Woo Seok has spoken publicly about his sister's influence on his career path during an appearance on "You Quiz on the Block". He revealed that he initially dreamed of becoming a pilot because of her role as a flight attendant but later developed an interest in modeling and acting after observing her past work in modeling.
The actor also noted that there is a five-year age difference between them.
Separately, a report from Naver noted that IU and Byeon Woo Seok's K-drama "Perfect Crown" is making waves globally, particularly in the U.S.
It became the first K-drama to stay in Disney+ U.S. Top 10 for 21 consecutive days as of May 3, 2026, according to FlixPatrol. This is notable because rom-coms usually face stiff competition from genres like crime and sci-fi in the U.S. The series has also ranked in the Top 10 across 47 countries, showing its broad international appeal.
Domestically, the drama continues to perform strongly, topping viewership in the Seoul metropolitan area and nationwide, especially among the 20–54 demographic. It also remains high in integrated TV–OTT buzz and cast popularity rankings.
Set in a fictional Korean constitutional monarchy, "Perfect Crown" follows chaebol heiress Seong Hee Joo (IU) and Prince Yi An (Byeon Woo Seok) as they challenge societal constraints while pursuing their destinies. Episode 9 is scheduled for May 8 on Disney+.
