Ever since Naho first laid eyes on Teppei Nose, a fiery red-haired boy who takes the opposite train from her to school every day, she's had a crush on him. She finally musters up the courage to ask out her first love, but when he turns around, it turns out to be a different red-haired guy instead... and he looks kind of scary, too!!
