The church bells rang every morning through the quiet town. To everyone, Father John was a priest should be—kind, patient, gentle, and ready to listen. No one questioned his warm smile or calm voice. No one suspected the truth. Because "Father John" didn't exist. Behind the white robes stood Jeon Jungkook, the most feared mafia boss in the world. Cold. Cruel. Merciless. His name alone made rival organizations hesitate, and traitors never lived long enough to regret their betrayal. Yet even Jungkook wasn't untouchable. After a brutal war between mafia groups, his advisors urged him to disappear until the chaos faded. He agreed, not from fear, but strategy. A dead king couldn't rule. So they gave him the perfect disguise. A priest. He hated waking to church bells instead of encrypted calls. He hated white robes instead of black suits. Most of all, he hated pretending to be kind. Every blessing, smile, and word mocked he truly was. Still, he smiled, listened, and spoke softly. If he wanted to survive, the ruthless mafia boss had to remain buried beneath Father John. For now. Across the city lived Park Jimin, whose ordinary life ended when whispers filled the darkness. They became conversations, then commands. No doctor had answers. No medicine helped. He woke with bruises and lost hours he couldn't remember. His mother believed an evil spirit had attached itself to him. She took him from church to church, yet every prayer failed. Because whatever lived inside Jimin refused to leave. It had watched him for years. Curiosity became obsession. It didn't want to destroy him. It wanted to keep him, to claim his body until Park Jimin became nothing but a forgotten memory. With silky blond hair, pale skin, and gray eyes, Jimin looked otherworldly. Behind those eyes, an invisible battle raged. Each day the spirit grew stronger, and Jimin weaker. Neither he nor his mother realized the next church they entered hid a priest who wasn't a priest at all.
