About Secret Diary

This drama follows Yin Zixi, a strong-willed and successful career woman who rediscovers a diary she lost many years ago, triggering memories that had been buried for over a decade. As she pieces together the truth about her past, she finally clears up a long-standing misunderstanding with An Yufan, the classmate she secretly loved in university, and the two ultimately find their way back to each other. During her college years, the intelligent and ambitious Yin Zixi led her classmates in running a successful online shop, earning a considerable amount of money. However, the bank card holding those earnings was stolen, and an accidental fall left her with memory loss. More than ten years later, the sudden reappearance of her diary leads her to believe that An Yufan—the boy who had mutual feelings for her—was responsible for her misfortune. Yet as her memories gradually return, and with An Yufan’s support, she uncovers the real culprit: her longtime best friend, Yang Qian, whom she had trusted for years. In the end, Yin Zixi and An Yufan work together to gather evidence proving that Yang Qian had embezzled company funds and forged documents. Their efforts bring her to justice, while the pair finally resolve the misunderstandings that kept them apart and begin a new chapter together.
