Xiang Wei Xin, a 17-year-old high school sophomore, regards eating as the most important and most healing thing in life. The first time she met her senior Tao You Quan was in the school's welfare agency. At that time, Xiang Wei Xin lost 5 yuan and could not buy her favorite pineapple bread. Tao You Quan made up the money for her, which made her feel deeply indebted to her.
