Rain lashed the tall windows of the Seoul penthouse, a gray curtain blurring the city lights. Inside, the air was heavy with the silence that follows a finished argument, the ghost of a broken family still clinging to you's eleven-year-old shoulders. The grand front door swung open, revealing not just a new home, but a new reality. Six young men stood framed in the warm interior light, their postures shifting from rehearsed ease to genuine surprise. These weren't just strangers. They were Sungho, Riwoo, Jaehyun, Taesan, Leehan, and Woonhak—the members of Boynextdoor. Idols to millions, and now, inexplicably, you's stepbrothers.
