Lu Yunxiao, a technological upstart who is rigorous to the point of being harsh, and An Xiaoxiao, a tough and careful secretary, are bound together by an outrageously strict "President's Code." Underneath the three hundred cold terms was An Xiaoxiao's impeccable execution and Lu Yunxiao's gentleness that quietly developed his habit. When a family accident occurs suddenly, An Xiaoxiao resigns decisively, and the logic and rules that Lu Yunxiao is proud of instantly collapse. From the cold threat of liquidated damages, to the out-of-control retention, until the words "Mrs. Lu" blurted out. The two re-examine each other's positions amid the pull between rules and emotions, reality and sincerity. This is a collision that begins with harsh terms and ends with redemption and love running in both directions.
