I don't understand why some of the comments keep raving about cheol still wanting his family to like him. Like yea, if it was me, I would've cut them off but its NOT me and I did not have the same upbringing that cheol had. BUT as someone who does live in a community where family comes first, I have literally heard and seen of situations similar to cheols (although fortunately, not as bad either) and, while some of them did cut off their parents in their adulthood, it still wasn't as easy as deciding that one day, you just move out.
Mind you cheol's in highschool during this. I really believe that, if you have the time to think about a 15 year plan, surely you could've thought of other ways to rid of cheol's family. I am still firmly in the belief that minyoung should not have outed cheol to is /EXTREMELY/ abusive father.
With all that said, I do like how ruthless minyoung is lol. I both love and hate that he outed cheol bc 1) it was cruel of him but also 2) i like me some crazy yandere hehe
