I'd just like to point out that the seme is a beta and the uke is an omega. So by omegaverse rules, there's really nothing biological going on there. All of it is emotional and psychological. Like, the omega has a choice to leave if he wants to coz a beta can't mark him.
But other than that, rant ahead(づ￣ ³￣)づ
Yes, but the psychological and emotional things are related to the omegaverse. The hierarchy of the omega vs beta vs alpha is present in both the seme's frustration (always pushed aside because alphas who, through their biologically enhanced whatever, are a lot more likely to be chosen for a job than him, a beta - at least from his pov), and in the seme's reasoning as to why his partner is but a "sex toy" (because he's an omega and by the rules of the omegaverse, they are pretty much at the bottom of hierarchy).
But I agree, the uke is not very smart to stay with a man like that when he has a choice. ╮(￣▽￣)╭
See that second story? Those are the reasons I hate omegaverse.
I'm sorry for the rant to follow.
[spoilers and bad language ahead]
That piece of shit beta seme, omg, I would kill him myself if I could. Two-timing the poor omega and and his fiance and then taking his frustrations out on him like that, bitch no. You had sex with that poor guy, then beat him and told him his only worth is being there for sex... (╯°Д °)╯╧╧
Quite a shame that a good story like the first one was paired with this bloody thing.
I understand some might like this, and that's fine, different tastes suit different people. But it's a no-no for me.
