cuz he's an interesting FICTIONAL character in a FICTIONAL STORY.
I mean, I agree that he's an interesting character. But I don't know, he's such a smart guy, yet he dealt with his pain in such a terrible way! (also sorry if I'd upset you - I don't mean to offend anyone personally) ^^
Why do you like/support him? (I'm genuinely curious)
He's manipulative, selfish, and a serial killer. There are many people with bad pasts, yet they don't kill people! They deal with it in healthy ways (therapy, sports, music, etc.) Sangwoo doesn't deserve any slack, what he deserves is therapy in jail.
