I am Supreme

Yuan Xi had been the secretary for Gu Hanchen for five years, working tirelessly without a single day off. Not only was she overworked like a horse, but she was also slandered by Gu Hanchen's fiancee and her friend, Miss Chu, who accused Secretary Yuan of delusionally hoping to turn from a sparrow into a phoenix and become the wife of President Gu. No longer able to tolerate the treatment, Yuan Xi handed in her resignation letter. After resigning, the once overburdened secretary surprisingly turned out to be the legitimate heiress of the wealthiest family in Jiangcheng, the Chu family! Back at the Chu household, Yuan Xi discovered that the family had taken in an adopted daughter, Chu Yan, who had been standing in for her. The false heiress was bright and unrestrained, rightfully considered the unrivaled young mistress of Jiangcheng. Even after the return of the true heiress, Chu Yan remained the celebrated young mistress while Yuan Xi was invariably seen as a mere shadow when compared to Chu Yan's splendid life. Yuan Xi's husband did not even own a house in the center of Jiangcheng. In contrast, the impostor Chu Yan was set to marry into one of Jiangcheng's top four wealthy families, the Bo family. Everyone in Jiangcheng ridiculed Yuan Xi for not having a life as fortunate as the false heiress, nor a discerning eye. That was until the day when Mi Chen was listed on the stock market, and Yuan Xi swiftly rose above her own father to become the new wealthiest person in Jiangcheng. On the day Yuan Xi's child was born, the established noble Huo family from A City announced with great fanfare the joy of welcoming a new grandson... Yuan Xi had always thought that her marriage to Huo Shiyen was merely a shotgun wedding, and that Huo Shiyen had someone else he considered his childhood sweetheart and sweetheart under the moonlight. Only later did she realize that she was, in fact, his cherished childhood love.
