17-Year-old Lin Ye was dragged into the neon dark alleys of Binnan City by his father's gambling debts - his mother's dialysis fees were hanging over his head, and the salary at the convenience store was far from enough. He clutched the folding knife handed over by Brother Hui and became a "marginal person" running errands for the gang.
Neon signs dazzled his school uniform, and the light of swords reflected in his eyes until he met Su Xiao who was investigating the cause of his father's death. Two teenagers entangled in darkness, one struggling for survival and the other running for the truth, found in each other the light to fight against the abyss.
This is not a story about a hero, but about an ordinary teenager on the edge of the underworld, using obsession and goodwill to break through the path of youth.
