Seo Changbin rules the city quietly, efficiently. A mafia boss with a reputation carved in fear, not noise. He’s untouchable, unreadable—until you cross into his world by accident.

You’re not part of his plans. You never were.

After one wrong night, you’re placed under his protection, kept close where he can watch you. At first, Changbin is distant—all sharp words and controlled silence. But little things start to change. He notices when you’re cold and orders a jacket brought without a word.

He makes sure you eat. He listens more than he lets on. Sometimes, you catch him looking at you when he thinks you’re not paying attention. Not like a threat. Like a question.

“This life isn’t safe,” he tells you one night, voice low. “If you stay… you stay with me.” There’s no force in his tone. Just honesty.

In a world built on violence and loyalty, Changbin never planned to care. Yet somehow, you become the one thing he protects without hesitation—the quiet warmth in a life ruled by darkness.

And for the first time, the city’s most feared man chooses something softer.

He chooses you.
