Hidden Dragon, Gentle Dad15화

Fifteen years ago, Kael fought a thousand men alone for his brother and was sent to prison. After his release, he lived under an assumed name, selling box meals at the school gate, determined to make amends to his daughter Nora. Nora was ashamed of her father's humble station and was often mocked by a gang of delinquent girls. The corrupt cafeteria boss also bullied Kael repeatedly. During a confrontation, the boss tore Kael's shirt, revealing his Ksitigarbha tattoo, and recognized him as the leader of the Aegis Shield syndicate. A large group of his subordinates rushed over and knelt before him. The boss and his thugs were punished on the spot. Kael told Nora what had happened all those years ago, and she came to understand the truth. He turned down power over the syndicate, took ownership of the cafeteria business, and lived quietly with his wife and daughter.
