Is rape a rule in most omegaverse manga???

Yes and he will probably be assaulted next chapter lol ( my guess though from the message he received ) let's replace rape and put " sexual abuse of ukes/omegas ( because women probably are having the same shit) in omegaverse

completly agree

Ugh, I do, too. Sadly. Cross my fingers and hope not, but that's what I think will happen.... T_T
