Aiko hates her name, her gender, and the man who turned her into a victim of sexual assault. Most of all, she hates the world itself.

Ko, who goes to the same boxing gym as Aiko, has a dark past—he was sent to juvenile detention center for killing his father. He seems strong, someone who has faced his trauma. Watching him, Aiko starts to believe: If I continue to box, maybe I can have hope in living my life for just a little longer.
