By chance, Lu Mingchuan became the new clerk of a grocery store on Mingjie. In Mingjie, a street where humans and ghosts coexist and are entangled in obsessions, he confronts all kinds of supernatural beings and human customers, and is immersed in strange and funny trivial matters every day. Under the guidance of Hua Sang, Lu Mingchuan understood the true meaning of Mingjie: the relationship between humans and ghosts is not absolutely good and evil, but a story connected by love, regret, obsession and forgiveness. He helped Sun Xiaogan reconcile with his past family members, prompted Bai Qiyue to let go of her grudges, and provided Yu Susu with a chance for redemption. He also gradually grew up during the adventure and became a backbone bridge in the underworld. When the real world and the underworld collide frequently, everyone needs to face the choice between good and evil, and finally find a new way of symbiosis in forgiveness and growth.
