Xu Yanxi, 22 years old and weighing 168 jin, makes up her mind to lose weight. After eating fat-reduction meals and giving up, she scrolls across a video of a fat girl losing weight through online dating, and decides to imitate it: find a handsome guy online, get fiercely dumped, and lose weight drastically out of heartbreak. She searches for Fu Heng's photos, and after reposting them on an account, locks onto what she suspects is his burner account. The owner of the account is actually Fu Heng's older brother, Fu Yanzhi. He recognizes the photos belong to his younger brother, but because he thinks her voice sounds nice, he plays along with the mistake and replies, "Your taste is alright." The two begin a sweet online dating tug-of-war across screens, each harboring their own hidden thoughts.
