A high school story centering around Kim So Eun, a timid girl with an ordinary life who gets invited to a school "drawing" club, after which point she begins to encounter "fantastical and extraordinary events." So Eun will suddenly find herself the leader of the club, and go on to build a strong friendship and even love relationship with the other five male members.

Each episode contains particular "missions" that have to be carried out, and in the process So Eun comes out of her shell and draws out her bright, lively personality.
