An ordinary parking dispute makes Xu Anning see through the unfairness in the workplace completely. Clearly someone else hit her car, yet the leader demands that she apologize first. Thinking the matter ends here, she never expected that projects would be seized, responsibilities would be shifted, unreasonable overtime, and performance adjustments would follow one after another. Facing grievance after grievance, Xu Anning no longer chooses to endure, but instead uses facts to reason and uses rules to fight for justice. From an ordinary employee asked to admit fault, to a key figure driving company change, she finally proves that reasoning is not refusing management, and holding on to principles is not deliberately making things difficult for others.
