Financial Director Zhao Jianhua and his wife Su Qingwen have been married for three years and their relationship is stable. One day, he unexpectedly attended a wedding and discovered that the wife who was supposed to be the "bridesmaid" was actually the bride, and the groom was her so-called "cousin." Later he learned that his wife's real name was Su Yuqing, and she was the only daughter of the chairman of Jiangnan Textile Group. She married him three years ago while concealing her family background in order to experience an ordinary life.
