Not asking for financial support was her decision for certain reasons i support that. They broke up so she took the responsibility of her child. I just think without wanting any type of support after a period of time she could have informed him about the existence of the child may be after him turning 18 atleast .
Because he’s trying to control his sons life, Felix isn’t a teenager or kid anymore he’s a grown adult and can date who he wants but his father wants to put his own opinion in when it’s not his place. I understand he didn’t know about Felix but it’s not his right to control his job, family, and lover
I understand what you mean but pretty much all bl dads have done the same, some even go over board. It's surprising that Mr. Yang hasn't even kicked Gio to the moon because of the way he acts and jokes around. But yeah, I understand why it is something that people are pissed off about but what I can't comprehend is the way some people already have "death threats" towards his character.

Can anyone please tell me why you guys hate his father? I feel bad for him, imagine not being able to raise/support your own child because you had no clue he even existed and the fact that he raised a son that ended up hurting his biological son whilst betraying the company. He doesn't seem such a bad man, I just wished Felix's mom could've asked for support from him especially when they were struggling financially.
