In classic shounen romantic comedy, two roles are ever-present: the Lucky Pervert boy and the Violent Tsundere Girl.
What if those roles were switched around?
The protagonist, Matome, finds herself bound in the curse of the Lucky Sukebe(Lucky Pervert) inherited from her father, who married the Violent Heroine. Fate pulls her together with her schoolmate, Morishima Tsudoi, who inherited the Violent Heroine curse from his maternal family, as he stays at his aunt's house after circumstances brought him there.
