The yankee Shishiou was challenged to a fight and ended up with a bloody head injury (even though he won). At a drugstore he stopped by, a part-time worker, Maya Kisaragi, talked to him without any fear and was even worried about his injury. He fell in love at first sight and confessed his feelings to her!But she rejected him, saying, "Yankees are a bit..."!?

The love fight between a foolish, devoted Yankee and a high school girl working part-time at a pharmacy begins!!♡
