My boyfriend has Asperger's, so i was really intrigued, but don't like serial killer genre. The Aspi part was not developed at all, big minus. Character development poor for a k-drama. But i did like the set up of 3 friends, sex with the same person, shaman lesbian... But the script needed much work. Suprised that comments on police, in k-drama police never solves anything.
All other cinematic aspects are gr8 lighting, editing, directing, acting all felt perfect.
