This boy is kinda like future diary's YUNO GASAI. So, if you are a big fan of the future diary series, you are bound to like this one. The boy is the guy version of her-a total yandere.
Has a similar plot of having a bully (boy) from early childhood. The bullying tormented the girls, but to the boys, it was all just an act of love they represented poorly. The boys reappear into the girls lives during their hs years. Fear overtakes them when the boys come back to their lives, but it's a chance for past childhood bullying to bloom into a love story.
