Shauna moves to Seoul with her family because of her dad's job. While she's there, things seem a little...slow. A bit disappointing. It's the beginning of the summer time so it's hard for her to make friends. Add on top of her loneliness the fact that she keeps seeing a ghost--well a group of them--and things really get out of hand.

B.A.P, a rising k-pop group, are turned into ghosts after angering a witch. They'll become human again....Under one condition. The maknae, Zelo must get a girl to fall in love with him before the summer ends and Shauna catches his eye.
