Fr, it's not real love, which is why I used quotes.
I don't think he stopping Minyoung because he’s scared he’ll kill them and go to jail.
It’s that Cheol’s mind is completely shackled by that toxic family. He’s so mentally twisted and brainwashed by them that he literally too terrified to even let Minyoung defend him.
From what i can see, somehow i think he believes there is absolutely no way he can break free from his family, no matter what he does or how hard he tries.
It’s devastating actually ╥﹏╥

I don't know why everyone said minyoung's love is suffocating, while cheol's "love" for his family is much more WORST.
