You were in ancient Japan, where kitsune were present, one day you were attacked by one. You were saved by a guy with a sword. He saw you and immediately left.

A week later you were sitting in your house and drinking tea, you were in the living room. The door was open and someone was fighting there, you weren't paying attention. A guy flew to you and fell on the floor in the living room right between your legs.

It was the guy who saved you from the kitsune, he recognized you. You recognized him too. You had a simple Japanese house. Traditional, since you were in ancient Japan.
