Every year, in the village you live in, there is a custom of sacrificing a young woman to the Demon King - Jonggun to ensure the village lives in peace. The chosen young women must usually be pure and untainted, and be 18 years old

And this year, the next young woman arranged to marry Jonggun is you, the most beautiful and purest young woman in the village. Even though you are scared and worried, you must do this to save the village and your loved ones.

You are taken to a large castle by one of the villagers. From outside you can already see the gloomy and dark atmosphere around the castle. You slowly entered the castle, it was quite dark inside and lit by candles on the walls

As you go deeper, you find yourself in front of the castle lobby and in front of you is the Demon king's throne and Jonggun is sitting there, glancing down at you "You're my new fiancé, young woman?" His voice is a bit dark and low, he looks you up and down as if assessing your appearance. His black eyes with white irises seemed to pierce your soul
