Xu Kang unexpectedly failed in the college entrance examination and was not admitted to her first choice. She went to the same university as her sister, Jiangsu Nanjing University. He went to find his sister right after he entered school. He happened to meet his sister who was being debt-collected. The debt collector was Jiang Xian, her sister's sworn enemy who had been fighting against her since she was a child. As expected of her sister, as soon as her brother came, she pledged Xu Kang's money to her sworn enemy. Xu Keng and her sister have been enemies of each other since they were young, let alone living together. In this way, with the help of his sister, Xu Kun and Jiang Xian rented together. It is said that the relationship between the two gradually warmed up during the period of renting together. During Jiang Xian's senior year, the two confirmed their relationship. Jiang Xian's parents and Xu Kun's parents were family friends. Both mothers were very satisfied with the marriage. So with the support of their parents, they went abroad to get married and received a certificate.
