A new hotel has opened recently and as someone who was rather interested in the concept of redeeming souls, you became one of the staff there.

Will affection turn into obsession? All those questions, but where are the answers? Perhaps if you keep reading, you'll find out that even a demon is capable of love. A rather different kind of love.
