Lin Wei, a capable project director, was unfairly suppressed at Daystar Group where she had worked for five years, and was forced to resign under the dual pressure of career and family finances. At the same time, Song Zhiyuan, who had a deep relationship with her, landed as vice president of the air group. His return seemed to be the initiator of Lin Wei's predicament, but he unexpectedly re-appointed her.
The two intersect again in the workplace. They seem to be opposite superiors and subordinates, but in fact they are both deeply involved in a well-planned betrayal mystery seven years ago. One of them was pushing forward the project in the open under pressure, and the other was investigating the truth in the dark. Through forced joint efforts and cooperation, they gradually discovered the misunderstandings of the year and the unchanging concern for each other.
As the investigation deepens, all clues point to the seemingly kind-hearted department director Zhang Mingyuan. He is not only the culprit who framed Song Zhiyuan and forced Lin Wei, but he may also be related to Song's father's car accident that year. After a thrilling confrontation that exposed Zhang Mingyuan's crimes, Song Zhiyuan and Lin Wei not only cleared their grievances and regained control of the company, but also discovered the secret connection between their parents' generation.
In the end, under the reflection of the city's fireworks and the peak of prosperity, the two protagonists untied their past knots and confirmed their feelings for each other. However, they also knew that the road ahead was still full of challenges, and they would work together to "walk against the light."
Keep up the good work. Optimistic about you
