Yoona is a girl who likes to dress as a guy and pretend to be a guy. That's her secret.
Jaebum is someone who thinks he turned gay because of Seungchoel who is actually a girl, Yoona.
But Jaebum found out that Seungchoel(Yoona) is actually a girl and not a guy.
Will Jaebum be angry at her or will he confess to her?
