Teenager Lin Yu is accidentally dragged into an S-class horror ghost city copy, binding the identity of a milk tea shop owner and low-level tea-making talent. While other players dodge monsters to escape, he relies on making various milk teas by hand, using unique deliciousness to awaken the sealed taste of the eerie. A crowd of fierce and eerie beings line up every day to punch in and drink tea, and collectively protect the stall when things happen. In the end, Lin Yu completes the hidden redemption mission with kindness to win an SSS clearance, and even gets the permission to freely enter and exit the copy!
