REMINDER: K/S IS NOT STOCKHOLM SYNDROME
an insane amount of feelings for Sangwoo WAY BEFORE anything happened at all. He didn’t develop them as a defense mechanism because he was abused, which is what happens in Stockholm Syndrome. He merely didn’t lose his feelings because of the happenings, which is pretty expected considering his disturbed personality (let’s not open that can of worms here, now)
What K/S has is in fact Lima Syndrome, which is when the abuser starts to sympathize with the victim.
