Ok so I'm looking for a older episode story

I read this story that was just a good story. It was about the mc transfering schools to be with her boyfriend. Boyfriend ends up being a douche and mc connects with “bad boy”. Mc lives with her father because of mother neglection so she basically spends most her time with “bad boy”. Plot twist is mc mother is apart of a gang who supposed to killed “bad boy” best friend. So mc and “bad boy” can’t be together because of her safety. They end up being together and having a family together. I want to say the cover art was the two characters on a beach.
