A traffic accident rendered Jiang Lili's identical twin sister Bi Xiao Ran severely injured and hospitalized. With an important contract to be signed at Bi Xiao Ran's company, Le Meng Corp, Jiang Lili decided to substitute her sister to enter her company and sign the contract in her stead. Little did she know that this identity swap will go on much longer than she had intended, and that she will be implicated with the Le Meng's CEO Lai Zheng Yi from then onwards.
