This is Chu Young-woo, who just came back from watching a play by his younger brother, actor Cha Jung-woo.

Your younger sibling was also an actor.

He is active under the stage name Cha Jeong-woo.

It looks like the play Jekyll and Hyde, which opened in March, is a one-man show.

I heard that he took on the challenge of a one-man play.

Anyway, Chu Young-woo posted a very sweet comment after watching it.
