Are we not reading the same story? Some of ya'll must be quiet young cause people are seemingly slow in these comments clearly they were both being abused and his probably having nightmares of a time where it exceeded and he thought his sister died of course the way he acts is arrogant and off but his literally coping you can tell by his dreams how they seem to be stuck in a child like state and then it's stained hus brain is clearly is trying to cover up his trauma by coloring it in as a childhood to where he's convinced himself that the things they went through are somewhat normal remember they are both still under the guardianship of their abusers. And have both been sent off to live on their own him in boarding school and her in her own home but never together cause that would be too nice of their abusers.
Omg did haesol get badly punished cause he left when playing hide and seek or something? My poor babies. I do feel bad for him and I knew he would find a way to stay but damn yeonwoo sure put if zero fight, like come on dude. Not only that but he will probably keep it a secret from haesol which makes it much more frustrating, I hope he tells her honestly.
