I don’t remember the name at all so got no clues to give about the title however I have gotten an ad for it on YouTube from Lezhin multiple times and told myself I would check it out later and never did. I think the main character moves to a different city or she comes back to school all due to bullying(I think)? The mean girl likes her but in the ad we find out that the mean girl ain’t a girl but A GUY and he seems crazy but has a crush on her
