Future time scientist Chen Yichu embarks on a journey of time travel in order to change a love tragedy. He transformed into an "uncle" and walked into the world of young Huang Yisheng and gave him a diary. From then on, he began a life and death game against time. Later, "Time Traveler" started from Huang Yisheng's middle school days. Chen Yichu transformed into Ye Zhiqi and became Huang Yisheng's classmate. However, the reality was beyond his expectation. He originally thought that he could change history and prevent Huang Yisheng and Han Kewei from being together. But in the end, not only did they come together, but their histories were surprisingly similar - Han Kerang had a car accident on the way to meet Huang Yisheng. The story is not over yet. After graduation, Huang Yisheng met a girl who looked very similar to Han Kewei. She said that she was the future Han Kewei and left. After many twists and turns, Chen Yichu revealed the secret of the "Time Diary". In order to save Han Kewei, Huang Yisheng decided to travel to the "past" of time to prevent her from coming. However, the car accident still happened, but the person killed was Huang Yisheng. Is this the price of being a time traveler? What is the truth of the story?
