Yanagisawa Aiku is president of the flower-arranging club. Because she has very little members, her club will soon be closed down. To prevent this from happening, she demands to the student council president that he shouldn't close it down. The president, Hosaka Ryousei, said he wouldn't close it down only if Aiku would go out with him. She agrees and steadily falls for him. But there are rumours that Aiku falls in love with a girl and then dumps her to go with another. Is Aiku just one of those girls to him?
