In a city ruled by fear and power, BTS are the unseen kings of the underground world, commanding loyalty and violence in equal measure. At the top sits Jeon Jungkook—the youngest mafia boss the city has ever known, cold to his enemies and dangerously devoted to the one person he refuses to lose. But one night changes everything. A simple dinner turns into chaos when a rival gang launches a brutal drive-by attack, shattering glass, peace, and innocence in seconds. When Y/N is caught in the crossfire, Jungkook’s world fractures—and the empire he built becomes a weapon of revenge. Now, with war rising between syndicates and betrayal lurking in every shadow, Jungkook must choose between his crown… and the person who makes him human.
