Can’t remember the name

I’m looking for an Alpha and omega story, where the Main character is an Alpha with a bad personality. An omega with a collar transfers to his high school. You later find out that they knew each other before, and this specific alpha bit him while they were playing a game (when they were young). You also find out that b3cause of this bite, the omega experienced heat syntoms early, and his older brother rapes him. Thanks in advance!
