Suzune's mother is a flower arrangement artist who runs a flower arrangement class. Tatsuya, the only son, didn't think her mother was funny. When he was a child, he was taught flower arrangement, and because of that, he was labeled as a "sissy guy." One day, Tatsuya hears that his admired classmate, Yui, is transferring to another school. Suzune suggests to Tatsuya, who is worried about giving a gift to Yui, who is separated from her, "How about arranging flowers and presenting it?"
