DoJin eldest brother, who in the family pic looked like his dad has 2 sons. They were both featured in the chapter where they appeared around 9/10 I think. And both are alphas. His brother who deals with perfumes has no partner, and neither does his older sister who owns the store. So he has 3 siblings,2 boys and 1 girl and 2 newphews confirmed. Grandparents going to get a 3 rd grandchild.
Yea I want to see this as well, because Hyesung fears his father will hate or use him if its revealed he is an omega. Yet Dojin's family has been shown to want omegas in their family. So it would be really great to see them dote on Hyesung (and the kid, if its an omega) when they find out.
I get that Dojin doesn't want the trouble that would come with his family finding out, but I really hope they do, because I expect it would one be entertaining. At least I hope so.
I wonder what would be the reaction of dojin's parents when they know their youngest have his fated one already and to all haters, let's all be romantic in heart shall we?
