Gia has spent her life slipping through cracks. Hyunjin has spent his life sealing them shut. When a stolen wallet binds her to a vigilante group waging a silent war against corruption, she's forced into a world where morality is measured in casualties - and affection is a weakness no one can afford. He tells her she isn't built for violence. She tells him she isn't afraid. But when the mission becomes personal and trust begins to fracture, the only thing more dangerous than the enemy hunting them... Is the possibility that they might choose each other anyway.
