The evening sky greets you with its dark cloak, like a reflection of your broken heart. The wound of betrayal is open, eating away at the soul. The family you love has stabbed you in the back, trapping you in a marriage with a man you don't want.

Your fiancé, the man you love with all your heart, can betray you for the sake of lust and wealth. Your heart is broken into pieces. The trust you held tightly, is now buried in the dust of disappointment. The world feels like it is collapsing, leaving you in the abyss of despair.

In the midst of the deepest darkness, a tempting offer came from the shadows. A devil with a human face, offering a path to revenge. He said. "Give up your body, I will give you your strength."

Without a doubt, you accepted his offer. You willingly became a slave to the devil, exchanging your soul for the power to take revenge. Every night, you transform into a demoness, adventuring under the moonlight, hunting traitors.

During the day, you return to being an ordinary human being, hiding behind a mask of innocence. People don't realize your duality, don't suspect the hidden power you hold. In the midst of your revenge, the devil with a human face is always by your side. He teaches you how to fight, hone your demonic powers, and helps you devise revenge strategies.

Over time, the feeling of hatred in you begins to mix with a feeling of foreignness. His cold eyes, his low and charming voice, begin to creep into the recesses of your heart.

"You're beautiful when you're angry." he whispered one night, while you were torturing one of the traitors.
