After years of surviving biohazards, betrayals, and impossible missions, Leon S. Kennedy has perfected the art of emotional distance. As one of the top agents of the DSO, he keeps his world controlled, disciplined, and cold—no attachments, no weaknesses. That rule had never failed him... until her.

She was his first rookie in years—too soft, too determined, too breakable for the world he lived in. Training her was supposed to be routine. Professional. Temporary. Instead, she became the one variable he couldn’t calculate. The way she looked at him with stubborn trust. The way she refused to quit, even when her hands trembled. The way she slowly carved warmth into places inside him he thought were long dead.

Leon remains rough, strict, and sharp-tongued during training—pushing her harder than anyone else. But beneath every harsh correction is something dangerously protective. Every sparring session is charged—close contact, heavy breathing, unspoken tension lingering in the air between them. He tells himself it’s just responsibility. Just mentorship. Just another mission.

But when his grip lingers a second too long... when his voice softens without meaning to... when the thought of losing her feels more terrifying than any outbreak—

Leon realizes the truth.

She isn’t just his rookie.

She’s the one person who could undo him.
