He plays Cha Do-hyun across all ten episodes of wavve’s 2026 BL series Summertime (하절기). Do-hyun is the harder half of the pair to play: the school’s model student in public, and privately fixated on his best friend for years without ever saying so. The part turns on what he does when a transfer student threatens the slow plan he has been running.
