It’s not an omegaverse but he did give birth to wo wo because he has both the reproductive organs. I can’t remember what chapter but when Nian was coming out of jail or something he overheard from his father that he is a monster(??) because he can’t figure out is he is a male or a female
The last ‘he’ is Nian
And sorry if this is confusing
Idk if it’s technically omegaverse but yes Ci Nian was born a “monster” with male genitalia as well as a uterus and he gave birth to Wo Wo.
Itz not omegaverse cause there's no heats, surprecents, marks, etc. Only a dude who has both reproductive organs UvU
Hey I'm confused is this like Omegaverse because did the main guy gave birth to wo wo??
