Born with a Yin-Yang body, he was in an inexplicable coma for three days before the college entrance examination and his soul strayed into the underworld. When he woke up and missed the college entrance examination, he came to Yunlan City to work as a delivery rider to follow his girlfriend. He unexpectedly awakened the ability to freely travel between the yin and yang worlds after falling asleep. He helped the dead souls in the underworld get rid of their obsessions and received corresponding gifts. From the bottom rider, he counterattacked and became a being that neither the yin and yang world dared to mess with.
