I don't agree with the comments that are slut shaming him, but what he is doing is technically self harm. Not being able to conceive a child does not mean you need to force yourself to sleep with others or resort to prostitution. He didn't even communicate with his partner about it, this omegaverse is really ridiculous, its just adding drama for the sake of it with zero logic.
Not y'all slut shaming sex workers. First of all, the uke isn't "sleeping around" for fun. Prostitution is a job just like any other means to put food on the table. Fuck y'all judgemental moral compasses. Not everyone has the privilege to work a "socially acceptable" job.
Second of all, this is an omegaverse story. In most omegaverses, omegas are already condemned to be in the bottom of society; their ONLY worth typically comes from being able to bear children for alphas. This uke can't. There goes the ONE THING that he should have been able to expect as an omega, but he doesn't even have that. I'd be devastated too. I think becoming a prostitute is a logical choice for him especially as an omega.
Yes, he's in love and the seme loves him back. It's clearly explained though that he comes from an elite family and the omega thinks separating from the seme is the best choice for the seme. I don't agree with making decisions like that for other people, but I have sympathy for his actions.
