Girls' Generation show support for Lee Dong Woo's play 'Hero in My Heart'!

Sooyoung started off by congratulating the start of the play, and then recommending the warm, feel-good story. The musical is actually produced bySM C&C, and tells the story of a blind actor who meets a girl who claims to be his daughter, even though he's had no idea.

Even if he doesn't know whether she's his real daughter or not, they become closer and closer. However, she has to leave him all of a sudden, leaving for a story of hero that seems plain, but is the greatest in a little girl's heart.
