This happens quite often...

MC goes through tough times because of the MLs actions and they forgive and forget. I'm not complaining, actually just here to enjoy the smut and the guide-verse story. Of course they're going to end up together or something. But if I were in that spot, where I was ostracized all throughout highschool just because a selfish mthrfckr doesn't want to share my attention with anyone else, IDC if it was out of love or obsession or whatever, that's just wrong. I had an ex who was like that, by the end of our 2-year relationship, I was exhausted with no one to run to because I didn't have any friends left and didn't manage to make new friends. Felt like a total loser and 10 years later I still never really managed to get my old personality back. Well, just saying it's tough and if I were the MC, I won't ever get into that looming toxicity. What am I saying? I'm still gonna enjoy this manhwa anyway.
