MC is a scumbag, seriously: Be nice to the isolated and disliked girl to make her dependant on you. Then start being cold to her to make her more desperate and confused. Then switch back and forth to mess with her head, then when she feels she can't live without your support, coerce, gaslight, manipulate and brainwash her to make her your obedient sex slave...The MC is a grade-a asshole. Like holy fuck. I get being angry with her for hitting him and not apologizing and stuff, but in no way did she deserve this bullshit. Worst part is, in that kind of environment and situation, he probably could have eventually gotten her into his bed just by being nice to her after she started being shunned by everyone else, without all the evil coercion and manipulation. It would just take longer.
