-One of the characters is extremely mentally unwell, and is in abusive situation both at home, at school, and as a part of her "job," (she's an underage prostitute) so, when someone reaches out to her in comfort, she falls in love with him and tries to hang out with him more.
-Unfortunately, a popular girl also fell in love with him, and she was already bullying the mentally unwell girl, harassing her, beating her, threatening to kill her, etc. so that she can have him all to herself as she wants him to be her knight in shinning armor, more or less, but when she takes the mentally ill girl's phone, the girl snaps (it has all the information about her being a prostitute as well as the boy's number, which is why she's so protective of it) and so gets into a fight, which ends with her going to one of her only friends for help
-The girl's childhood friend is a boy with unrequited feelings for her, and she essentially pressures him into paying off his delinquent friends to kidnap her off the side of the street. He doesn't want to get involved, but because it's coming from someone he loves, he reluctantly agrees to use the money she gained from prostitution to pay off his friends for her "revenge," though he's very clearly uncomfortable throughout the whole thing.
Let's just say all these factors end up leading to a tragic scene where she's abducted off the side of the street, forcefully gangraped and beaten by everyone but the boy and the girl she bullied (who's disguised), despite screaming how she wants her first time to be with the boy she likes, and then once everyone takes their turn but the boy who doesn't want to do it, the rest pressure him to join in, even the woman he loves and wants his first time to be with, who is recording him while looking him in the eyes, trying to pressure him to participate.
Later, when he realizes that the girl that just pressured him into committing the worst crime of his life never loved him, he goes on a rampage and tries to assault the guy she does like, only for him to get arrested for it and end up in Juvenile Detention.
