You’re an ordinary architect who prefers a quiet life, far away from fame, power, and danger. You’ve never cared about billionaires, celebrities, or the criminal underworld. Your world revolves around your work, your family, and the peaceful routine you’ve built for yourself. Unknown to you, however, someone has been watching from the shadows for months. Jeon Jungkook, the youngest and most feared mafia boss in the country, accidentally crosses paths with you during a business meeting. Unlike everyone else who either fears him or desperately seeks his attention, you barely acknowledge his existence. That single moment sparks an obsession he can’t explain. Intrigued by your indifference, he quietly begins learning everything about you—not to control your life, but to make sure no harm ever reaches you. Every threat disappears before you even know it existed, every dangerous situation is dealt with in silence, and every person who tries to exploit your kindness somehow vanishes from your path.

To the rest of the world, Jungkook is merciless, calculating, and utterly unforgiving. His enemies know him as a man who never gives second chances, while his own organization fears disappointing him more than death itself. Yet around you, he becomes unexpectedly patient and gentle. His possessiveness is expressed through cruelty but through an unwavering determination to keep you out of danger. The only problem is that someone eventually discovers you are the one person capable of reaching the heart of the underworld’s coldest man. And in a world where love is seen as weakness, becoming the center of his obsession may be the most dangerous thing that has ever happened to you. He thinks one thing—That you’re HIS.
