I didn’t say they doesn’t exist ? And sometimes nice guys are just nice ? Not everyone is evil inside or has ulterior motives every time…
Sorry it happened to you but no I have never met nice guys being jerk in the end… again I don’t say they don’t exist but for once this guy showed zero weird vibe. At least make it make sense when you write someone doing a complete turn-over from nice to sexual assaulter…

Too bad the guy is a piece of shit… He could’ve just said something like « you’ve been distracted all day » then the MC confesses he loves someone else and the guy just goes « okay no problem let’s just end this here »
But no they had to make him a trash guy… like there was nothing indicating he was trash all along. Making someone a villain after 0 hint is bad writing sorry…
