Im not sure bro but yea I agree Kiheon did bad on their first, and he didnt give a sh!t after coz I mean if Im on his position my granpa just died and in the middle of mourning you gonna approach me to sleep with you I mean I would be pissed as hell like the disrespect was soo much and knowing Baek-yeo he was like his granpa's apple of the eye to the point that it's already sus. Not defending but being emotionally unstable and being approached like that figures why he was agitated.
Just because he is not overly sweet towards his son doesnt mean he doesnt care for his son. He is a bachelor and all of a sudden he got told that he has a son after a one night stand it obviously wont sink in right away. We didnt even see him denying the boy, he provides and takes him to places too. If youre also going to point out why Kiheon would send him with his friend's family just as so he can "spend time" with Baek-yeo, their kid is old enough to enjoy a little field trip without his parents. Makes a good training ground to be independent. I mean I know it is also their intention to bring up selling the land for investment but also coz they suddenly became family kinda skipped the honeymoon part right? It might not show but Kiheon is really whipped with Baek-yeo. He liked him eversince they are young.
The next chapters will show some backstory about granpa etc, why he was desperate to have a kid with Kiheon. I dont want to be misquoted so Im just telling based on what I saw.

Those are all excuses for treating the uke badly. A bad past or history doesn't make up for being an absolute trash human. He literally shouted at him that he was a slut as he roughly fucked him. He yells at him constantly if he speaks up for himself, and when he missed his son. I don't care if he likes him, he needs to actually treat him better and make him feel secure not worry the seme hates him
Dont worry guys ML will not do anything bad to MC. He is just really business minded lol but he likes MC very much. If you remember the woman who was like rumored to the ML, ML even said that woman's face is nothing compared to MC's beauty.
