"Honey. Don't you want revenge on those who killed me?" The portrait of her dead husband spoke to her. It happened right after she finished holding his funeral. But, "Make a contract with me. Give me your soul, Aub." A sweet voice and affectionate gaze. Yet, an eerie unfamiliarity he failed to completely hide. 'This is not my husband.' The man in the painting—he was a demon wearing her husband's shell. Even so, she willingly sold her soul. To find the culprit who killed Camille and plunge a knife into their heart. But... "You are truly awful. Your sweet, rabbit-like husband is waiting for you with all his heart, yet you go around flirting with other men and won't even take a walk with me..." Wait, this is strange. Did I adopt a dog instead of a demon? But the bigger problem was elsewhere. "You can take my time whenever you want. No, honestly, I'd prefer it if you did. "What reason do you even have not to love me? We look exactly the same. "Aub. Your husband right now is me. You need to focus on me." ...Obsession wasn't part of the contract. Besides, you aren't even my real husband to begin with, so why are you being so sweet? You're a demon!
