His dad lost his ability to feel emotions and is dependent on his dominant omega partner. His partner comes first, no matter what. Pheromone accumulation caused brain damage, now he has to stay near his dominant omega and his pheromones for the rest of his life to not worsen his condition.
He also has trauma, he is afraid that one of his children turns out like his own dominant alpha father. He never wanted that many children.

Oooh that kind of explains why he was emotionally so cold but still tried his best to comfort his child by saying he will buy another bird for him. I wonder where his other dad is? I mean I can't expect the story to be all happy since it needs a driving plot to build up an entire Universe. But that's so cute that he prioritize his partner over anyone even children

The story of thr grandparents is dark.
I just wrote something on what you ask on another comment

in the last ~ third of my comment.

I totally forgot ist was also mentioned in Kiss me if you can. Was only certain that is was in the parents story just checked.
Koi, his omega father asked Ashley to go see Chase, but it doesn't go into detail, it's only mentioned that Koi told him he was sorry that his bird died, but Chase didn't react. The manhwa adaption left that out, it should have been in this chapter.
There is more in the parents story, it resulted in getting Chase that role in that chocolate commercial.
Is his dad OK?? Or is he twisted like the rest?
