Kimio Suga gets trapped in a gym locker at exactly the wrong moment: when his female classmates return from PE. When Nozomi Komine discovers him there, he expects disaster. Instead, she covers for him, and he goes home relieved. That relief does not last. Nozomi, a quiet girl in his class, turns out to live across from him in the same apartment complex, and she soon texts him with a demand. She wants the two of them to show each other their bodies through their windows whenever she asks, and she has the locker incident to hold over him. Reluctant but cornered, Kimio goes along with it while searching for a way out, and along the way he finds himself growing closer to her. A three-episode comedy, ecchi and romance OVA built on blackmail and bad luck.
