Imo accusing someone of rape is maybe even worse than commiting the rape itself. Be it some loner guy with few to no friends or a celebrity, no one really will belive you, that you didnt do it, but you get stigmatised in the same way. Your reputation is ruined with horrendous consequences, e.g. no good jobs if at all, destroyed circle of friends and you went into jail if found guilty. Also, even if youre declared innocent, everybody in your social enviroment will doubt you and never see you the same again.
And this is the premise the author chose for them to interact, yea great.. not. No wonder the ratings are almost at 5...
But dont get me wrong, real rapists should get punished by all means, just saying that the framing is no cavaliers delict. The Female MC didnt do it, but blackmails him with doing it. And yeah, given the status, looks and circumstances of them, as an outsider I would probably belive the girl, if I had to judge. So the threat is real.
