Single father Chen Mo is an ordinary delivery boy, raising his autistic daughter Duoduo alone. The weight of life left him breathless. When the pot of sunflowers planted by his daughter withered, his tears unexpectedly opened up a heartbreakingly tender ability - he could hear the "language" of potted plants. From then on, every takeout he delivered was accompanied by a pot of "little life" that could understand the family's hidden worries, and a warm "tip" written on a card. The "miracle flower" he planted made his daughter call "Daddy" for the first time; the "plant heart language" he conveyed quietly repaired the cracks in the parent-child relationship in the corner of the city. When the capital giants who covet his abilities step by step, those families who have been warmed by him build the strongest walls for him. This is a story about listening, about fatherly love, and about healing the world in the softest way.
