Transmigrating to become a giant panda cub, Lan Xiao stumbles into the field of vision of a scientific research live broadcast and encounters a panda named Chu Yi. Lan Xiao mistakenly takes the male Chu Yi for an auntie bear, but the other party frequently comes to feed, accompany, and take care of it, causing many interesting events. Lan Xiao tries to climb a tree beyond its capacity and gets trapped, and Chu Yi runs off to notify humans for rescue. Afterwards, Lan Xiao reaches the age of independence and is driven away from home by its mother, Da Lan. Homeless and in heavy rain, it is very lonely, but unexpectedly Chu Yi voluntarily leaves its inherent territory and chooses to follow Lan Xiao, thus starting a new life.
