The month she turns 18, Kim Seren is taken into the castle with a request from the Queen; to occupy her sons in their boring and unfulfilling castle life. She is a fun-loving (not very girly) girl, notorious throughout town for her trouble-maker acts. Seren accepts, almost reluctantly, and thus starts her new life teaching the boys how to have fun.
