Liu Qimeng was often bullied by naughty boys when she was young. They laughed at her for being lonely and helpless, causing her to squat on the ground and cry.At this time, grandma Liu Xiuying arrived in time. She encouraged Liu Qimeng to be like the brave little Wukong and not succumb to fate.With her grandmother's encouragement, Liu Qimeng was no longer afraid, and the children who bullied her also restrained their behavior.

Afang caused Liu Xiuying to be injured due to her own fault. After she severely scolded Xiaoqiang, she hurried to the hospital to visit.Although Liu Xiuying was unhappy, years of friendship made her finally choose to forgive Ah Fang.When Yu Changjiang saw that Liu Xiuying was safe and sound, he felt relieved and left with A Fang.Liu Xiuying wanted to change her body with her granddaughter, but failed repeatedly, so she considered going abroad to undergo plastic surgery so that her granddaughter Liu Qimeng could fall in love with Sun Kai smoothly.

Sun Kai rushed back to the hospital eagerly, wanting to recognize the “Little Wukong” in his heart, but unexpectedly discovered that the person in the corridor was Liu Xiuying, who looked like Liu Qimeng.He mistook Liu Xiuying for Liu Qimeng and handed her the album.At this moment, Sun Kai finally understood the truth: Liu Qimeng and Liu Xiuying had swapped bodies.Liu Xiuying did not hide anything and confessed all this to Sun Kai.However, she felt that now was not the time to recognize each other, because Liu Qimeng (now living in Liu Xiuying's body) was seriously ill and could not withstand the stimulation; moreover, the mismatch of their identities also made her feel embarrassed and worried about affecting her reputation.Therefore, she firmly opposed any intimate behavior with Sun Kai before her body was changed back.

On the other side, Liu Qimeng (as Liu Xiuying) went to Lao Wang for a haircut, while the real Liu Xiuying brought a fruit basket presented by the neighborhood committee to share with everyone. This was her reward for her courageous act.At this time, Sun Kai came to send flowers and invited Liu Xiuying (actually Liu Qimeng) to go out to relax.Sun Kai's attentive care made Liu Qimeng (Liu Xiuying) feel warmer.When talking about the company's plagiarism incident, Liu Qimeng (Liu Xiuying) was worried and wanted to reveal the truth, but she looked like a grandma in the mirror, which made her hesitate to speak.The two spent a happy time together, and when they parted, Liu Qimeng (Liu Xiuying) gave the captured doll to Sun Kai, and they were inseparable from each other.

When Sun Kai came home and saw his grandfather practicing calligraphy, he felt guilty.He failed to find a store that restored the photos, and his grandfather was depressed because he missed his old love, which made Sun Kai blame himself even more.

Liu Xiuying (as Liu Qimeng) invited Jiang Wen for a drink to test her relationship with Sun Kai.Jiang Wen appreciated Liu Qimeng's straightforwardness and suggested that she decide whether to disclose information by punching.Not to be outdone, Liu Xiuying was defeated one after another and went home drunk, feeling very embarrassed.Liu Qimeng was full of apologies when she learned that her grandma was drunk because of her affair with Sun Kai.

The grandmothers continued to learn hip-hop dance under the guidance of Teacher Xiao Lu, and their skills became increasingly better. Teacher Xiao Lu spoke highly of their performance and expected them to win awards in the competition.

When Liu Qimeng (Liu Xiuying) went to work with Zhang Youzhi, she found that many people had gathered in front of the company. They accused Wang Yiming's company of plagiarism.When Wang Yiming couldn't argue, Liu Xiuying (actually Zhang Youzhi's boss) stepped forward and claimed that Zhang Youzhi was the real person in charge of the company, thus diverting everyone's attention.This move made Zhang Youzhi feel embarrassed and angry.After returning to the company, Wang Yiming was determined to investigate the matter thoroughly.He asked Sun Kai to express his position, and Sun Kai promised to find out the truth within a week, otherwise he would resign.After the meeting, Sun Baifen talked to Liu Qimeng privately and persuaded her to leave the company to preserve the company's reputation.
