The down-and-out young man Gan Chao rescued the crashed interstellar animal Amu and took it in with care. Gan Chao's father, who is addicted to gambling, comes to the house to press for debts and commits violence. A Mu awakens in his human form and transforms into Mr. Mu to rescue him. With his extraterrestrial abilities, Amu opened a milk tea shop, and the popular drink became a great success, and Gan Chao also became a major shareholder. During the entrepreneurial period, the two encountered pressure from their peers and dark forces one after another. Amu repeatedly used supernatural powers to resolve crises, but he would revert to dog form when he consumed energy, was afraid of fire, and was about to return. In the end, the dark forces kidnapped Gan Chao, and Amu broke through his fear of fire and worked hard to save him. Gan Chao knew A Mu's interstellar identity, and the two joined hands and formed a special bond.
