I’m not too knowledgeable about omegaverses but I think it mean Hyesung can’t have sex with anyone but Dojin or his body rejects it or something like that.
I’m not sure though, will have to wait til the next chapter to confirm it.
In omegaverse if an omega is bitten on the neck by an alpha during there heat they are mates and the omega is only able to have sex with there mate but an alpha can still have sex with anyone. A bonded omega is sick if it has sex with someone other than there mate.
Hope that helped (●'◡'●)ﾉ( also google about omegaverse it's more detailed)
When I alpha bite omega's neck, Omega can't sex with anyone except his alpha.
I think it’s like mates/partners, in this story there was knotting during sex at some point and I think knotting can form a bond, in some other omegaverse stories people become a bond by biting, https://www.google.co.uk/amp/haberkonium.tumblr.com/post/146555840779/omegaverse-explained-knottingbonding-edition/amp this link will help explain.
Oh thank you guys! Maybe it happened when they knotted. Coz I don't think Dojin has ever bitten him in the neck
Bond? What does that mean?
