I'm annoyed that Evan gets what he wants, even if he ruins himself. I'm concerned for Victor as to I he still has his sense of self. He was the only really innocent person in this story. The story is actually good and well written, its the first yaoi devil that I read that actually acts like what you expect of him, not creating a version where they act like humans and change for love. He never really felt love. He was just obsessed. But still, this is not my cup of tea, I do prefer the lovey dovy nonsense demons even if it's a little dark, so I don't think I'll read this again.
I'm confused about the contract, once its made with a devil, isn't the soul automatically the demons? Even if you don't want to give it? That's why it is a contract and not just their words.
