I don't know if you noticed (or maybe I remembered wrong). But we rarely hear Cadiel's thoughts AFTER the ball which was where he found out Ellen was the girl from his past. Which means that he was sincere before, but after finding out he had these evil thoughts.
This story confuses me a bit. We spent a major portion of this manhwa reading the story in Caidel's perspective. And the impression I got was that he really is a good person. If the story suddenly makes him into a bad person, it just wouldn't makes sense. I would understand if he was a character where we never got to hear his inner thoughts, but only from someone else's perspective. But we were able to hear a lot of Caidel's thoughts. And how can you deceive someone in their own head. It doesn't make sense. So I hope the author doesn't makes Caidel evil somehow.
Also when Noah asks Eleanor whether she doesn't know Caidel's true identity, does he mean the fact that he is the son of her master?
I'm also a bit confused about the fire that was caused by Eleanor and the fire at the Earl's home. Were they in the same area? Or were they two separate incidents. Because if it were the same incident, that occured because of the contract, how were some lives spared while others were not. Should it not have taken every life?
