Our heroine Nazuna is the top student at her school because the person who used to be on top got played by some manwhore and became a hikki. Her parents are busy with their work and decide to go overseas leaving Nazuna alone at home. They don’t want her to be all by herself so they send her off to the same school that her older brother Wabisuke attends. She moves into the dormitory there and while looking for her stuff, runs into a The Manwhore Club (+1 lesbian) who demand that she give them money for hitting on her. ( ´_ゝ`) Nazuna’s like “wtf no” but Wabisuke tells her that these guys will screw you over if you don’t do as they say because they’re drowning in money. Nazuna not sure what to do consults the dorm teacher Reito-sensei, but sadly for her, he’s also part of the manwhore club. The only way to clear her debt is to make Wabisuke become a member of the club and for Nazuna to date all the members until they get bored of her. However if she ends up falling in love with one of them, she will have to pay the debt and Wabisuke will be part of the manwhore club forever!! Will Nazuna be able to overcome being a prisoner of love?
