A guy and his newlywed wife moved into an apartment and they lived next door to a grumpy old man. Whenever there was a little noise at his house, the old neighbor would knock on the door and scold him, he even grabbed the husband's shirt and threatened him. The next times he came knocking on the door were just an excuse when he first saw Honoka Tsuji's sexy body and he had bad intentions. And then one day when Honaka's husband was away, he came knocking on the door again.
