Jiang Beiyue, who was once the operations director at Ruike's headquarters, hid her identity to work as an administrative staff member at a partner company in order to care for her ailing father. Over three years, she took on all kinds of miscellaneous chores, only to be regarded by colleagues as a tool person good for nothing, suffering contempt and exploitation. Unfair salary adjustments and endless extra work made her determined to resign. Just when everyone from her former company was full of anticipation to attend a meeting at Ruike's new branch, they shockingly discovered that Jiang Beiyue was none of other than the head of the branch office. Those who used to look down on her felt ashamed and embarrassed, while the intern Xiao Wang, who had been enlightened by her, stuck to principles and grew rapidly, receiving an interview invitation from Ruike and completing self-transformation.
