Suzune's mother is a flower arrangement artist who runs a flower arrangement class. Tatsuya, the only son, did not find such a mother amusing. When I was little, I was forced to learn flower arrangement, and because of that, I was labeled as a "feminine guy." One day, Tatsuya hears that her admired classmate, Yui, is transferring to another school. Suzune suggests to Tatsuya, who is worried about giving a present to Yui, who is separated, "How about arranging flowers and presenting them?"
