Irene is the leader and guitarist of a rock band named "Black Velvet". The group is pretty popular among girls because of their androgynous vibe and obviously because of Irene’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 leaved the group without a word, leaving an empty space for a possible new member.

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