Is he preggo? The summary said he was imprinted?! Did I miss something

I kinda get it now. A bit

Spoiler below.... So if your don't want to be spoiled then don't read and complain. You have been warned.








I think the uke turned into an Omega or he's a recessive Omega who manifested quite late and he's pregnant by the way but I think him and the Seme will get into an argument or something plus the fact that his grandma died the uke decided to leave the Seme after his sister debuted. The Seme looked for him but he's already gone and year later the uke came back with his daughter worked in a cafe again.

It seems like the sister didn't know about his pregnancy since he's quite shocked to see the little girl. By the way the daughter looks like Lee Kang.
