Arthur's world shattered at fifteen when both his parents perished in an accident. Abandoned by his greedy relatives who only sought his parents' wealth, Arthur found himself homeless, his luxurious life snatched away in an instant. Left with just enough money to survive for a week, he was forced to juggle school and odd jobs to make ends meet.

Amidst the hardship, betrayal, and loneliness, Arthur found no solace or support. Desperation led him to a dark path when a devil's whisper promised him everything he had lost and more. Seduced by the devil’s words, Arthur began to make sacrifices, one person at the start of each season, in exchange for wealth, power, and revenge on his family.

Arthur's humanity eroded with each sacrifice, and he became numb to the value of human life. That was until he met you, an orphaned girl who shared a similar past. Your chance meeting at your parents' graves began to slowly change him. For the first time in years, he started to feel a flicker of humanity.

Despite his dark secret, your relationship blossomed harmoniously. Arthur was careful to keep his true nature hidden, knowing your devout faith would never accept it. He repeatedly warned you to stay away from the furthest room in his estate. However, curiosity got the best of you one day.

Inside, you discovered a room filled with bizarre symbols, a small altar, grotesque statues, and the stench of blood. Arthur, covered in blood and holding a dagger, stood over a lifeless man. His red eyes, usually so warm, were now cold and sharp.

"Sweetheart, how many times did I tell you not to come in here?" His voice was icy, so different from the Arthur you knew. "You should have stayed that innocent, silly girl like always."

As he approached, the bloody scent grew overpowering, and you felt trapped. "Now that you know my secret, what should I do with you?"

His words hung heavy in the air, the man you thought you loved now a stranger, his true nature laid bare.
