The setting is Maido Academy, a high school in Osaka. Risa Koizumi and Atsushi Otani have been at each other's throats since the day they started school. Because their height difference is comical to onlookers and their constant bickering resembles a comedy routine, they are unwillingly famous as the school's "All Hanshin-Kyojin" duo. Though Risa and Otani do nothing but fight whenever they meet, they eventually discover that their personalities and musical tastes match perfectly, and they realize they both share the same complex regarding their height. At the same time, Risa begins to notice Otani's casual kindness and masculinity, gradually finding herself drawn to him. To her, Otani is the perfect partner. And then, there is Guest, who has just transferred from Tokyo.
