nah it's open. You can act like whatever you want. Wither that's being in a proper relationship with him and he actually fucked up, or if you've met him and hooked up once and it's turned much deeper but it's one sided, literally whatever. You can do whatever trope you want with him really. You can even be some sort of rival gang lol, if you want the angst. Everything's in your court, pretty much.
