@BlueBerryBabyBoy4444 But, oc, it's just one aspect, and there is so much more into it, every scene in this masterpiece adds a different layer of the whole picture, that I... I really can't explain it here any further, it's just not that kind of platform where you can discuss these kind of things, I mean, it's not something you can explain in 2-3- or even 30 comments here, it's way more complex than that, it deserves az least an essay, so... Instead, I suggest you check out real serial killers, especially Ted Bundy and Ed Gein. Sangwoo's personality and brain is kinda works as the mix of these two, with this of love-and-hate relationship with his mother, I guess the author inspired by them to some extent. (Ed by the sick relationhip and Ted by the lovely public personality that made him loved by anyone) Also, the Ed Gein case is probably the best and easily understable example to explain why do you start to kill or even ra** people because of you mom, meanwhile you don't have any incest thought.
