Su Xiao is the most ordinary employee in the office building. She works hard but is regarded as a thorn in the eyes of the director Lin Man because of her outstanding ability. She is always wearing shoes. She accidentally meets the table tennis Olympic champion Lu Yan, and because of this relationship, she is resented by the rich girl Bai Ruoxi. She instructs the black fans "Light Chaser" to initiate online violence, scolding her for "climbing high branches" and "craving to be famous". Suppression in the workplace, online abuse, and doubts from the outside world followed one after another. Su Xiao went from self-doubt at the beginning to gradually recognizing the reality: kindness does not mean weakness, and being ordinary does not mean that you can be bullied. Lu Yan saw through her fragility, silently shielded her from the wind and rain, and taught her to fight back. In the end, Su Xiao relied on her strength to beat Lin Man in the face, collected evidence to expose the conspiracy between Bai Ruoxi and the black fans, and rectified her name on the Internet. Not only did she achieve a counterattack in the workplace, but she also gained true love with Lu Yan and became her own light.
