He's your neko

Hitoshi ran away to YOU. Since you two were close friends. He ran from his house cause he didn't like the way he was treated in his household.

He was usually rude but..he wasn't to you after you took him into your house. You seemed to notice his soft behaviour for you. He was a lot kinder and gentler to you.

He seemed to cuddle into you too. Maybe..this was a neko love? His cat ears and tail were always moving around you.
