Agree.
Both Sangwoo and Bum aren't normal, are disturbed persons in their own way. Bum was already in love with SW and when they collide, you get KS.
In this case, despite being a merciless ruler, the Lord doesn't enjoy killing people or hurting them particularly, when he kills, it's always to fill a precise plan. About NK, he hates what's done to him by the Lord and proof is that he had run away...
I wish people would stop comparing this to killing stalking lol
