omega and Alpha manga?

The one where they have to find their fated Alpha and Omega, and there was this guy that almost raped the omega in high school, and when they grow older that guy that almost raped him now has an omega. As a fuck buddy that works at a bar with a name tag that literally says he's a Omega, plus the bar boy might be a fated Omega to the guy that almost got raped's Boyfriend/Alpha
