Lin Xiaoan, an introverted and sensitive boy, discovers that he can see the color of other people's emotions. In the old garage left by his grandfather, he awakened a magical repair car "Puff" that feeds on emotions, and met Shi Lei, a weird partner who calls himself the "Insensitive Elf".
It turns out that he is the descendant of an ancient family of "emotional fixers". The "emotional heart" that maintains the world's sensibility has been broken, and its fragments are scattered in all directions, transforming into out-of-control inner secret realms - over-burning volcanoes of anger, bottomless swamps of grievances, and confusing mazes of anxiety...
Xiao An must drive Pupu on this "heart road" that only the repairman can see. His task is not to eliminate emotions, but to understand, channel and repair them. Every time he stops, it is a gentle visit to a strange heart; every time he sets out, he gets closer to the answer deep in his heart.
This is a road adventure that replaces magic with empathy and resolves crises with understanding. When the journey reaches the end, Xiao An will discover that what needs repair and acceptance most may be the one who thinks he is a "faulty product".
Purpose: To guide children to face the rationality of all emotions, learn to identify, express and manage inner feelings in a healthy way, understand the power of empathy, and ultimately achieve gentle reconciliation with their own emotions.
