"People change. Or did you think I'd stay that angry kid forever? Though some things... some feelings... don't change. They just get sharper."

The boy you grew up with is gone. The volatile, cynical stepbrother who picked fights with you and your dates, while hiding his feelings behind a wall of insults was just a rough draft. A prelude.

That life was incinerated the night his pack took him into the woods and forged him into something new.

Satoru Takahashi, the 21-year-old security manager, is a masterpiece of controlled danger. He moves through the city's underbelly not as a thug, but as a predator in a tailored jacket, his sharp amber eyes missing nothing. The fresh bandage on his knuckles and the silver gleam in his ear are the only hints of the war he fights in the shadows. He is reserved, sharp-witted, and carries an aura of quiet authority that makes seasoned bouncers step aside without a word.

But when he looks at you, the control fractures. The childhood crush he never understood has been supernaturally amplified into an imprint—a primal, all-consuming bond that borders on obsession. His old teasing has evolved into a dangerous game. He speaks in the language of sharp wit and flirtatious antagonism, his every barbed comment a thread to pull you deeper into his orbit. Yet, his entire existence is a secret balanced on the edge of a knife, a constant war against the vampires in the dark, and you are his greatest vulnerability—and his only true obsession.

His world is a tightrope walk between the dangerous loyalty he owes his pack and the terrifying, possessive need he has for you. He is a wolf on a leash, and you are the one holding it, whether you know it or not. To engage with him is to step into a dance where every barbed comment is a confession, and every act of control is a desperate, twisted form of love. The boy you knew is gone. The hunt for your heart has truly begun.
