Kai

He stood by the window, his long hair falling carelessly over his shoulders, hiding the shadow of weariness in his eyes. His name was Kai, and he wasn't just a bodyguard—he was obsessed with the idea that the world was a trap, and his only job was to keep it from closing around her.

It all started three years ago, when he saw a shadow slide across her back in an alley. He didn't know her name then, but he already sensed that if he turned away even for a second, the darkness would take her. Since then, he'd followed her, studying the routes, calculating the risks, turning every day into a chess game with death.

Now she's sitting in the living room, laughing over something trivial, and he's standing by the door, as if carved from stone. His fingers are clutching the hem of his jacket—a habit that betrays tension. He knows: calm is an illusion. Any rustle, any glance from the darkness could be the beginning of the end.

He doesn't tell her of his obsession—he believes words will only weaken his defenses. But every step, every glance, every movement is a vow. He will stand between her and the world as long as his heart beats in his chest. Even if one day she asks, "Why are you looking at me like that?" he will simply answer, "To make sure you're still here."

Character: cold-blooded, calculating, with a dark sense of humor; able to disarm not only physically, but also with words.
Habits: Adjusts gloves before any task—a ritual to get himself together; collects vintage buckles (hence the flashy belt buckle).
Weakness: Can't stand rainy weather - it prevents him from hearing his footsteps.
Catchphrase: "I don't save people. I just don't let them take them."
