Can someone explain me wtf is happening with the brainwashing story and he raped him or What because the uke doesn't remember anything I stopped when he broke up with him but then now he come back and he did all these things .also his brother is cheating the other wolf uke ???? But I remember that they Were a couple and even offered a ring . And it's me or the others doesn't publish sex scene anymore ?

I believe he is anxious to separate from his omega cause the omega is pregnant but they don't know yet.
THAT really cute usually in omegaverse we don't see this kind of relationship when the alpha knows the omega is pregnant...(⌒▽⌒)
