Ayumi Mitsuya learned young that survival was rarely graceful. Sometimes, it looked like unevenly cut hair, bedroom doors left open, blood hidden beneath long sleeves, and laughter loud enough to stop anyone from asking questions. Growing up as a founding member of the Tokyo Manji Gang, she spends her youth fighting for the people she loves as if loyalty alone could keep them alive. But then she meets Rindou Haitani-the boy she should have hated, the one person who understands the violence in her without mistaking it for all she is. Between lies, gang wars, stolen nights, bruised knuckles, and promises made by children who believe they can outrun consequence, Ayumi and Rindou build something dangerously close to forever. But as friendships fracture, bodies fall, and Tokyo becomes crueler, loving each other begins to feel less like salvation and more like another wound neither of them knows how to survive. They were never each other's cure, only the last thing left standing after everything else became ruin. And when everything finally began to fall apart, they were left with only one promise: "Even if everything falls apart... stay with me."
