Man idk this trope never made sense to me.
ml got raped then the person who raped him had a kid without his knowledge.
Mc's side : bro ran away and raised a kid but then got raped
Honestly I'm sorry to say but i would hv aborted or put the kid up for adoption (if it was irl situations) so yea cant feel empathy or sympathy.
If the omega/female gets pregnant but loves the alpha/male and wants the kid I think he would keep the child.
If the omega/female has been in an abusive relationship then it depends on if they love the kid or not. If he/she can separate the child (who's innocent) and the relationship with the abuser then they can still have one.
But if not then the scenario you have described.
So the seme was raped , then he rapes uke ??? Wait what?
