Dad*
He kept saying shit like the kid shouldn't live in bad environment and deserve better living condition but he's the one who abandoned euiyong in the first place. He knew damn well that sohyuk is a shitty person, who don't give a shit about his son. Euihyun was forced to raise and provide for that kid. What kind of good environment does he expect euiyong to provide when he's living with his bastard father?
Good for him that he got better life now. But it also means that if his life never improved, he would've just let euihyun take care of euiyong forever
Bitch i wanna slap the shit out of that mf
The kid's mom had no right to just get the kid and pretend that abandoning the baby since his birth was ok! If he wanted to be in his life again I think having meetups or even inviting his brother to live them would have been better!
