Seven names feared by the entire underworld. Namjoon. Seokjin. Yoongi. Hoseok. Jimin. Taehyung. Jungkook. Together, BTS controls one of the most dangerous mafia empires in Seoul — ruthless, untouchable, and willing to destroy anyone who threatens them. But when classified government files containing every crime tied to their names are discovered inside an abandoned facility, the group is forced into a deadly mission to erase their past before it ruins everything they built. During the mission, they find her. Bruised. Bloody. Barely alive. Y/N should have been nothing more than another witness left behind in the chaos, but the moment Yoongi sees her, something stops him from pulling the trigger. Against the members’ wishes, he brings her back to the BTS mansion — a cold and mysterious fortress hidden deep within the forest where danger lives behind every locked door. Surrounded by men who don’t trust her and secrets no one will explain, Y/N quickly becomes trapped inside a world of violence, betrayal, and obsession. While Jungkook grows protective and Taehyung’s fascination with her turns increasingly unsettling, Yoongi fights the strange connection pulling him closer to the girl he swears means nothing to him. But as enemies close in and hidden truths begin unraveling, Y/N discovers the terrifying reality behind the files — her name was in them too.
