The lovelorn Tong Jiajia accidentally rescues Bobo, who claims to be "the last mermaid on earth", and is forced to start living together because he swallowed the dragon beads that kept him alive. Bobo is an arrogant and arrogant man with a sharp tongue and a golden fish tail. He loves to eat steamed buns, sings out of tune, is extremely mysophobic, and loves to tease Tong Jiajia, who has just lost his love. Tong Jiajia calls him Master Bobo! The mermaid was leisurely and elegant, lying on his side in the bathtub, showing off his big golden fish tail: "According to you humans, life-saving grace must be repaid with flesh and blood! Either give me back the dragon beads! Or Mr. Bobo will eat you!" In order not to be eaten, she fed, changed the water, and brushed the fish tail every day. Her eyes were shining, and she was extremely dog-legged. Jia Jia fantasizes every day about sending this overbearing mermaid who tears sharks with bare hands back into the sea to save her own life: "Today I bought 20 buns and stuffed them between Mr. Bobo's teeth. The buns are on the table and I am next to them. Do you think the buns are much more delicious than me?"
