I have a lot of thoughts about whb. On one hand, the pacing is awful, some of the story decisions are just dump (like the poison making us psycho-project into Leviathan's memories) and a lot of problems being presented and never acknowledged (like Minhyeok's relationship with MC). On the other hand, I adore the way they present the demons.
A lot of media that includes demons as protagonists/love interests get stuck between a rock and a hard place, not wanting to present morally bad actions yet at the same time not wanting to make them saints with no wrong doing. But whb does something interesting with the concept and makes the demons more human in a sense. They are capable of doing great acts of kindness and evil, but the thing that makes them devils is that they are true to their desires. It's one of my favorite parts of the story.
