Kappei, a short yet extraordinarily skilled athlete, resides as a guest in Akane's home. Despite harboring affections for her, his romantic pursuit is challenged by an unusual competitor – Akane's mischievous dog Salomone. This canine foe not only sets cunning traps for Kappei but also serves a unique role in elucidating the rules of various sports. Kappei, with a penchant for white women's undergarments, often finds himself in amusing attempts to lift skirts.
