Hong Kong, 1987. Beneath the neon glow, undercurrents stir in Kowloon Walled City. He Ci, a gentle, sensitive, and kindhearted young man, ends up there by accident. His only source of warmth is Su Rou, his childhood sweetheart, who grew up by his side and now works at a cha chaan teng. But his rival, Chen Yaozu, repeatedly frames him, hoping to steal Su Rou away and drag He Ci into the mire. When all seems lost, He Ci awakens a golden finger called “Heart Decoder,” which lets him see other people’s emotions and weaknesses. With this ability, he navigates Hong Kong’s underworld, the clashes between police and criminals, and the feuds of the jianghu, forging a path to a comeback with the quiet resilience of a deer. Every time he is backed into a corner, he turns the tables with kindness and intelligence, leaving his opponents shaken.
