A lot of people seem confuse about this.Let me explain,So basically dojin and hye sung are originally from the other manhwa(the original one is not omegaverse,just like normal) that this cretor also create,but the creator maybe stop at the part where like dojin and hyesung had S** and it just end there. So we dont know if they actually end up together or not so the creator decide to make a story about hyesung and dojin but in omegaverse.(Idk if this true bcus i tried digging up about them and this all i can find.Hope this help)
Ignore this,just continue reading whatever u reading...
