Six months ago, she vanished. Atop investigator in Special Investigations, known for her precision and quiet intensity, she had been relentless in her work — especially after her younger sister was kidnapped. When the department failed to make progress and leads mysteriously stalled, frustration turned into something darker. She began digging on her own. And then one day, she disappeared without a trace.No resignation.No body.No explanation.Only silence. Keigo had never expected to fall for her — but he did. Hard. She was sharp where he was reckless, grounded where he was impulsive. She understood him in ways no one else had. And just as he was beginning to imagine a future with her, she was gone. For six months, he searched. Used connections. Pulled favors. Bent rules. Broke some. Nothing. Until bodies began to surface. Men with ties to trafficking rings. Corrupt officials. Individuals connected to cold cases — including her sister’s disappearance. Each death was deliberate. Clean. Methodical. Almost surgical. Not chaos. A hunt. And the pattern is unmistakable. She didn’t disappear. She went to war. Now Keigo is faced with a truth he never wanted to consider: the woman he loves is alive — but she’s operating outside the law, dismantling a corrupt network from the shadows. She isn’t reckless. She isn’t spiraling. She’s calculated. And she won’t stop until every person involved in her sister’s kidnapping is erased. As the line between justice and revenge blurs, Keigo must decide where he stands — with the system he serves, or with the woman who abandoned it. Because when he finally finds her again, she won’t be the investigator he once knew. She’ll be something far more dangerous. And this time… she might not let him pull her back.
