Born as a daughter of a gangster family, Arashiko Hana shark longs for "ordinary romance". However, the young head of the flower shark group, Sumikawa, always bothers me! People are scattered just because Sumikawa, who is said to be the worst in the underworld, is nearby! However, the distance is always close! If you fall in love with him, you can't go back to "normal" anymore. A heroine who never wants to fall in love x a young head who plays with her, a love struggle without justice, breaks out here!
