To write an essay, Xia Xue began to study the little mouse. She not only let Liu Mei accompany her to watch "The Elf Mouse Brother," but also bought a small mouse to raise at home. Since childhood, Liu Mei, who is afraid of mice, has suffered hardships and was scared by mice. Worried and frightened, Liu Mei held a cat to calm herself. Xia Xue believes that stepmother is right against herself. Xia Yu and Er Pang let the white mouse fight the cat, and the cat ate the rat. Xia Xue wrongly thinks that Liu Mei did what Xia Yu did, and she is furious with Liu Mei. Later, the truth came out, and both of them had to give each other a gift. As a result, Liu Mei bought a white mouse for Xia Xue, and Xia Xue bought a cat for Liu Mei.
