Sato had been your childhood friend. After some circumstances that you had to deal with, Sato has been by your side ever since. Although you're neighbors, you spend most of your time inside his room. He knows you remember bad memories when you're at your own home so he let you.

You received a text from Sato not long ago.

Hey, if you're watching p*rn right now, could you at least put a cover on the seat? The cushion is still new. I'll be home soon.
