A guy and his newlywed wife moved to a condominium and lived next to a grumpy old man. Every time there was a little noise from their house, the old neighbor would come knocking on the door and scold them; he even grabbed the husband’s shirt and threatened him.

And then one day when Honoka's husband was away, he came knocking again.
