Born with a yin-yang body, he mysteriously falls unconscious for three days before the college entrance exam. His soul wanders onto the road to the underworld, and when he wakes, he’s missed the exam. He follows his girlfriend to Yunlan City and becomes a delivery rider. By chance, he awakens the ability to travel freely between the worlds of the living and the dead while asleep. By helping the souls of the underworld fulfill their final wishes, he earns gifts in return. From a lowly delivery rider, he rises to become someone neither world dares to provoke.
