Crimson Code

She solves murders. He survived one.

Y/N is no ordinary criminologist-
At just 24, she's the youngest and most feared in the field. Cold, brilliant, and always ten steps ahead of the criminals she hunts. Her past is sealed. Her heart, locked. But when a string of chilling murders leaves behind a trail of playing cards and no clues, she knows it's not just a case.

It's a message.

From him-the Crimson Dealer.
A serial killer who has killed five men, all in the same calculated, twisted way... and who once tore her life apart.

Enter Jeon Jungkook, world-famous idol and the only witness to the latest murder. Scarred, shaken, and hiding secrets of his own, Jungkook is forced into YN's world-a world where blood speaks louder than words, and trust can be fatal.

But the deeper they dive into the mystery, the closer they become.
And the closer they become, the more dangerous the game gets.

Because the Crimson Dealer doesn't just kill.
He plays.

And in this game of lies, shadows, and secrets...
Love might be the deadliest move of all.
