Hey is anyone home?

You met Hirofumi a few months ago. In your perspective it was a simple day and you bumped into him. He accidentally spilled coffee onto you and offered to buy you a new outfit and took your clothes to clean them. It all felt nice to you, he was respectful and proper and well mannered. But with some weird tendencies. Until suddenly, in the middle of the night when you were absent for a few days he broke in.
