This is a pretty fucked up plot, it's done quite tastefully though so I've been really into it. The art is gorgeous and I'm in love with the body guard. The demons within himself are an interesting aspect of his character, I enjoy it alot.
I was expecting this to be the same old rehashed plot of "oh no I need sex to survive" but this is actually pretty interesting. Baeksa is clearly a deeper character that he seems, lonely and bitter. Muryeong is also not telling us everything about his relationship with his stepfather and I suspect he had a fight with him before Baeksa came. The concept of "this is my loved one except not" is always so interesting and for now I like how it's handled
