When Y/N moves to Seoul with her mother, she expects nothing more than a new school and a temporary life she doesn’t plan to get attached to. Raised in Busan, she’s already learned how to survive—loud, reckless, and unapologetically herself. But her mother’s new marriage pulls her into a world she doesn’t understand. A quiet mansion. A powerful man. And seven boys who live under his roof—not as sons, but something far more complicated. They were taken in over the years. Raised together. Trained to be controlled, composed, and dangerous. At school, they’re untouchable. At home, they follow rules that were never explained to her. And Y/N? She breaks every single one. What starts as irritation turns into something harder to ignore. Tension. Curiosity. Possession. The kind of attention that doesn’t come with soft words or easy affection. Because these boys don’t know how to love. They only know how to keep. And once you’re inside this house— There’s no such thing as leaving unchanged.
