I get what you’re saying and I agree with most of it but let’s not forget that Dojin manipulated Hyesung for a good portion of the book. About the trauma Dojin told Hyesung to just have the baby and that’s all, remember they had a contract, he was just upset that he couldn’t find some reason to manipulate Hyesung to stay when he jetted. People aren’t saying they hate the book they’re saying they didn’t like how that certain scene was portrayed. Like just because people are saying the didn’t like a scene doesn’t mean they should be told not the read the book, like if I said “oh you don’t like the fact that they had a child, you’re a hater, you shouldn’t read the book” that really doesn’t make sense. Not everyone is gonna like everything in a book and that should be respected. Ion that situation I feel that Dojin didn’t have to go all stalker on Hyesung they could have talked it out but the never actually had any communication skills to begin with so...
I understand what your saying. I didn’t say hate the book, I said if they hate the dynamic, you can skip this particular chapter.This types of dynamic happens in most manga/manhwa and I think that the author only made this as a small plot or a segment of comedic jealous, a small drama in their relationship. Its a trait in Dojin, “bad habits die hard.” Also, time changes someone. When Dojin told Hyesung to have the baby, he slowly falls in love with Hyesung, its the connection and bond of an alpha to his omega. And most importantly..
This is an omegaverse:) as such, Alphas are more possessive towards their bonded omega and are strictly sensitive towards them. I get that people keep calling Dojin manipulative, but this is Omegaverse. Its a universe where 3 types of gender exist, with traits that made them that way. Dojin too is a dominant. He protected Hyesung, showered him with money and love, tried to win his heart and he is responsible to his duty as a father and money maker of the family.

You all have to remember that Hyesung used to like Omegas. Dojin feels insecure because he isn’t what Hyesug likes, he isn’t Hyesung’s type:)
An example is you have a bf/gf that is attractive to girls/boys who have freckles. You don’t have freckles and notice that whenever a freckled individual passes you and your partner, they tend to lock their eyes on them, sometimes commenting or saying that Freckles are beautiful. Of course the first thing you would feel is jealousy and frustration, its normal, being a little concerned that they would probably leave you for the individual with freckles. Apply this tothe situation now.
What Dojin is showing is a normal feeling that usually expresses his feelings towards Hyesung. He’s concerned and he feels like one day he would loose Hyesung, again. Also this kind of attitude of Dojin is because of trauma. He lost his partner right after the birth of his son, you don’t know what kind of adrenaline he felt there. He may have even felt that Hyesung might run away with another. Because he thinks he isn’t good enough for him.This is just a simple, feeling of jealousy. Also, they’re married and have bonded, again, try imagining your significant other, for life, married:) staring at another person or locking eyes with another person.
And if you really dont like it or just hate this adorable dynamic, drop it, or skip this part of the story. The author only wants to make their manhwa more interesting since it has already passed its climax. This is a side plot, a side story. Take it or leave it.
I see this as only a dynamic or the little drama in the story. (●'◡'●)ノ
