Jeon Jungkook never thought the beauty he craved would turn out to be two different people. One - a phantom menace, an assassin too beautiful to ignore, too dangerous to touch. The kind of obsession that slips through his fingers like smoke, leaving him restless and hungry for more. The other - cold and precise, merciless and unshakable. A beast draped in silence, watching him with eyes that see too much, cutting him down without lifting a blade. Two faces. Two obsessions. And Jungkook, caught between beauty and beast, not realizing they share the same blood. Love. Hate. Obsession. In the end, it will destroy them all.

Kim Taehyung is known as the Devil in human form - cold, arrogant, feared by everyone around him. No one dares to stand in his way... until fate plays a cruel trick. Forced into an arranged marriage, Taehyung is paired with Jeon Jungkook - the sweetest-looking bunny boy, but with a bratty, sassy side that knows no limits. Jungkook makes it his mission to tease, annoy, and irritate the devil himself at every chance he gets. But Taehyung isn't called a devil for nothing. He's determined to show his bratty bunny why people fear his name... and in the process, he finds himself falling into a chaos of love, obsession, and unexpected softness he never imagined. A battle of sass versus arrogance, innocence versus sin, where love may be the only thing strong enough to tame the devil. "Arranged to marry the Devil, but I refuse to behave - Mission Bunny"
