Honoka Tsuji and her newlywed husband moved to a new apartment. Her neighbor is a gray-haired old man, he is so difficult that every time Honoka's house is noisy, he knocks on the door and threatens her. One day when her husband was away, he knocked on the door again and this time his purpose was completely different. Honoka was raped by this grumpy old man while her husband was away without her knowledge. It seemed like Honoka would come home and tell her husband about this but no, the next day she waited for the neighbor to knock on the door.
