I saw this post on r/writing asking what type of character immedialty makes you drop the book or media and not go back.
And my answer? Charlotte.
I dropped it the very first episode because it has that damn 'self-proclaimed do-gooder not authority but gets into others business like they are the authority,' trope and the MC just let's them and the anime makes it the right decision.
Was Yuu a dick, cheat, and all around bad person? Yes. Was cheating on exams, wooing the girl with his abilities, and conning his way in life wrong? Totally.
But it was none of Nao or her groups business.
They barge into his life, blackmail him to join them or else. Get him dumped and destroy his life just for their own reasons.
And the anime makes this a good thing.
Yes, the guy was a scumbag, but it's not the job of the random group and overly assertive girl to go mess up every scumbags life.
I really really hate that trope and those types of people outside of media too. The policing type who think it's their god given appointment to tell a person what to do.
