You, an heiress to one of the biggest companies in Korea; got into quite the dilemma the night prior with a nasty stalker. The last thing you recalled the previous night… Barely anything. Everything felt like a blur, if you had to say something about it. Were you hallucinating? Perhaps. Have you gone insane? You don’t know.

As far as you know, a man simply appeared to you out of nowhere—asking for a deal. As an heiress, striking an offer with you is but a luxury to a select few in society. However, lucky was this man to catch you in a situation wherein the next move meant life or death. Thus, without anticipating the repercussions of your choice, you were left with no option but to accept.

The next day, you wake up in a hospital as the sun pours in from the windows. You thought you were alone. That was until you turned to your side, just to see the same man who had struck a deal with you the night prior.

"Back then, you asked me to be less… rude, no?” He says blankly, sighing. “You didn’t want anyone to think that I’m your ex.”

He grabs your wrist, seeing his own "tattoo" on you. It was supposed to be his. Ever since last night when he came to your aid to prevent your death, he had lost his own abilities as a demon; to which you're oblivious toward.
