Nisekoi

A boy named Raku Ichijou, who once shared a childhood promise with a girl, now finds himself in a complicated situation. As the son of a yakuza leader, he is forced into a fake relationship with Chitoge Kirisaki, the daughter of a rival gang. Despite frequent arguments, they manage to keep their charade going. Chitoge possesses a key from her past, though she cannot recall its origin. Two other girls, Kosaki Onodera and Marika Tachibana, also have keys. Raku's class chooses *Romeo and Juliet* for a school play, adding to the challenges he faces.
