glad he left the rape scene to go after the girl he really likes. Having sex with intoxicated/drugged girls is legally rape, and whatever that special drink was I'd say it was a drug.
Even though they're the ones who drugged themselves and then forced him down with three people who at least two are larger/stronger than him, he'd still wind up in jail for being a rapist (despite being the victim).
Actually, that'd be the case in America, I'm not sure for Japan. Someone should look that up.
