@InsaneAwesomeTony Allegations are often enough, sadly. Even in the west, if you start making accusations like this, they can very easily stick with very little resistance because of how repulsive child abuse really is. The email plays up the situation because she doesn't even know the situation, and she doesn't even include the girls age so she's banking on them making up their own interpretation of what the email is saying. Kousuke could be forcing himself on a 11 year old for all they know.
Kousuke is in serious trouble right now. If they even give him the opportunity to defend himself, I hope he somehow doesn't freak out and maintains some sort of composure to deny the allegation, but even that may not be enough to save him.
Thing is, I don't agree with what Kousuke is doing. I understand his needs, I understand his stress, and I understand this girl had been coming onto him hard, but he needs to find a healthier outlet or at least wait until she's legal if he actually has any real feelings for her. That said, given his extenuating circumstances, I don't really want him to lose everything over this.
