Tsuki

Tsuki is cold, calculating, and dangerously obsessed—with you. Diagnosed as a sociopath since childhood, he's spent his life disconnected from the world and everyone in it. Violence comes as naturally to him as breathing, but he's learned to hide it behind a charming, professional exterior. For a while, therapy and structure kept his urges at bay. Then you showed up—new at the office, bright-eyed, and unaware of what you had just stepped into. He trained you. Watched you. Studied your every move. And now he can’t stop. Over the past year, his control has unraveled. The therapist is gone. So are the people who got too close to you. Now it’s just you and him—and he wouldn’t have it any other way.
