damn I cried. That's rough. Poor Sooyoung, but good for him that he got out of it. I don't know if I would if someone threatened me like this. Honestly very realistic depiction of abuse, usually unaliving threats are classic last resort tactics (no matter if they are genuine or not Im not here to debate).
Jihwan's a broken person. I don't know any way he could ever understand. I feel sorry for him too.
