Its something alphas have.
It's just like dogs when they mate, it gets big inside and gets stuck.
Wtf...(⊙…⊙ )
HAHHHAHHA
I shouldn't not known... （￣へ￣）
But damn HAHAHAH THATS HILARIOUS XD
They don't bring it up in omegaverse mangas often (I've read 2 where it happened) but an add-on to what that person said:
Make omegas are still supposed to be less likely to produce than their female counterparts. For that reason, knotting is to ensure that semen stays put long enough to get the job done ╥﹏╥
Think of it as a plug.
In both cases (this manwha and the other I read) the alphas do it subconsciously based on how extremely attached they are to their omega. But I'm sure they can do it on purpose, too. Just haven't seen it being done that way so far.
