Ji Dan asked Yoongi's best friend: "A lie a day, to me. That's all. I forgive you." It was quite the weird scene for Yoongi to watch. His best friend's mute sister as she forgave him for all the horrible things that he'd done in the past few years. "Uh... can I lie to you after breakfast?" Even so, this girl... was odd. Definitely worth his investment.

Demons. Humans. Death. Revenge. The demon of Revenge has chosen a new host, the unlucky Song Gamgi, to take its place. Gamgi holds all the power of Revenge, but to fully understand and embrace it, she needs to go through a series of tests: Power Demeanor Death, being the easiest. Never Rest In Peace, never live in peace, but Gamgi dies in pieces when she becomes a demon, trained by Kim Taehyung (demon of betrayal) and his six friends. Will she exact her element upon them? Or will she suffer in silence and self-hatred knowing she's fallen for her murder?
