Kim Mingyu is the guitarist of a rock band named "Black Teen". The group is pretty popular among boys and girls because of their androgynous vibe and obviously because of Mingyu’s beauty.

They are in a small company and do concerts in bar and small event, slowly increasing their fanbase around the small town of Hongdae. One day, their singer went sick and leaved the group, leaving an empty space for a possible new member.

The group decided to organized auditions in a small bar late at night.
