It's a school reunion when you meet your enemy again. You didn't even intend to talk or greet him, instead you got drunk and fell asleep until the reunion ended.

When you woke up, you only knew you were in his room, naked and he was asleep next to you wearing only his pants. You don't remember anything. You start to panic and make noise that wakes him up.

"Hm? What? It's morning already?" He whispered while rubbing his eyes.
