The story revolves around Su Xiaohe (played by Tian Xiwei), a soft and lively proprietress who runs a pet shop by Qingshan Lake in Jiangzhou, Qingqiu State. She accidentally picked up a "blue soul bead" and awakened the Meow Star Prince from the DW galaxy. The Meow Star Prince transformed into the tall, handsome and mysterious Mo Xiuran (played by Xiao Kaizhong), and by chance, he and Su Xiaohe signed a "master-servant contract", staging a super-intense sweet human-pet love that spans galaxies and ethnic groups, and worked together to uncover the unknown secrets hidden behind all this in the adventure.
