Stitched In Blood|| Jungkook FF

To the underworld, Jeon Jungkook is a legend.
Feared as the ruthless head of one of Korea's most powerful mafia syndicates, he built his empire on blood, loyalty, and absolute control. His enemies whisper his name with fear, while his allies would die for him without hesitation. The only person who ever softened the cold-hearted mafia king was his beloved wife, Jeon Y/N
To Jungkook, Y/N is everything.
She's the elegant, loving wife waiting for him at home after every bloody mission. The woman who kisses him goodnight, patches up his wounds, and promises him a peaceful future far away from violence.
But Jungkook has no idea...
His wife has been lying to him since the day they met.
Every night after he falls asleep, Y/N quietly slips out of their mansion and disappears into the darkness. While Jungkook believes she's peacefully resting beside him, she's wearing a black tactical suit, hiding behind a mask, and becoming the most feared killer the criminal world has ever known.
She isn't just a serial killer.
She is the anonymous leader of VICIOUS an elite underground assassin organization responsible for impossible assassinations, government-level covert operations, and the elimination of the world's most dangerous criminals. Every member follows only one person...
Boss Y/N.
Merciless. Brilliant. Untouchable.
She has left behind countless bodies, never once leaving evidence or witnesses.
For years, she's lived two completely different lives.
By day, she's the devoted wife of the Mafia King.
By night, she's the queen of death.
Neither the police nor rival syndicates know her true identity.
Not even her own husband.
But secrets never stay buried forever.
When one of Jungkook's mafia enemies begins hunting the mysterious assassin known only as The Crimson Phantom, Jungkook unknowingly joins the hunt, unaware that the woman he's searching for is sleeping beside him every night.
As gang wars erupt, betrayals unfold, and the line between husband and enemy begins to blur
