A Story of Love, Loss and Redemption PAPA «??» tells the heart-wrenching story of Nin (Sean Lau Ching Wan), a humble café owner whose world is turned upside down when his son Ming commits an unimaginable crime—murdering his own mother and sister. Diagnosed with schizophrenia, Ming is sentenced to indefinite psychiatric imprisonment until he recovers. Left alone, Nin leads a quiet, solitary life, burdened by memories of his lost family. Despite the pain, he continues visiting Ming twice a month, clinging to a single hope: that one day, his only surviving family member—the very person who destroyed their family—will come home again.
