A civil engineer who came next to the married woman Hiro came to greet him and looked at Hiro with a lascivious eye. Hiro complains that he can't stand the attitude of a civil engineer who doesn't make a fool of himself at home every night, watch AV at a loud volume, or sort out garbage. A civil engineer who had been harassed by being complained and thought that he was a good woman for a long time brought Hiro to his house and attacked him.
