I think knotting will seal the chances of an omega being pregnant, knotting is different from marking an omega though you're getting it mixed up hahah. Although it maybe hard because the doctor said hyesung cant get pregnany anymore :(
It's not about becoming mate but the alphas knothing themselfs inside omega when they want them become pregnant. It's like a way for their semen to say inside omega as long as fertilization occurs.
Knotting is supposed to act like a plug. The head of the penis grows so that the sperm won't escape the uterus once the omega has been seeded. It was a combination of Dojin's cumming inside Hyesung repeatedly, and Hyesung overstimulating him.
I cant answer this with a 100% certainty but a knot in the animal kingdom is used by males to assure that their "seed" is planted or what not usually they dont get small or go away untill they literally cant cum no more. And yes they have knot before and it doesn't change their relationship it just feels painful for the receiver since after a knot is made it cant be taken out and if tried its painful. Hopefully this makes sense.
Ohhh i see thank youu (づ￣ ³￣)づ
The knot in the omegaverse is something that belongs to the alphas. It'll block their penis inside the omega to make sure that the omega will be fertilized.
And, if an alpha and an omega want to be mate the alpha has to bite the neck of the omega.
But, you know, omegaverse is one those AU that can be change. Even if there're "rules" everyone can make it their ways. So who knows. But for now I guess the knot in this story is the definition i gave you above.
Based on the story, yes, they bonded.^^
I may be late, but what happend if they knot? They become mate right? But didn’t they knot it already?
