so far, the theme of this manhwa is:
if you're wanna go crazy, go all the way!

idk why but this manhwa is so satisfying (as an entertainment media) because for the other media all they can do to describe a char that is crazy or psycho is just from the words and a bit lack of self-restraint OR they go crazy but just for the main character (yandere type). too boring!
This one feels like whole. The despair and the feel that the other extra is fully displayed at the end of their wits is so good!
