He debuted as an actor in 2019, when he starred in a drama called In-Out Sider.

Two years later, he did a comeback together with VICTON. In 2020, he wrote a song called White Night that was a part of VICTON’s album, Continuous.

“I think I’m most interested in the part about not regretting the choice I made.”

“Don’t worry too much, because your worries will be resolved after a while.”

“I often think that even if I were born again, I wouldn’t be able to meet this kind of group again. When I’m alone at home while we’re on holiday, I think about the other members a lot. There are times when I’m at the dorm and get stressed over the various everyday sounds like people chatting in the living room, showering, or snoring, but when I’m at home I miss that.”

“Some people may think that we are growing at a slow pace, but we had made our own promise to take each step slowly. Looking at the bigger picture, I think we are doing a great job.”
