Ok but my question is aren’t marked omegas incapable of having sex with any other alpha except their marked one?? So why isn’t chase questioning that? Or are the laws of mark/bond different in this verse? Like iirc in kiss me liar omegas were also capable of marking alpha which is unusual to typical omegaverse but idk
