Time and Space Dream

This is a double-crossing story. The 18-year-old Yun Shu was supposed to enter the university campus, but she woke up in the morning and traveled ten years later, becoming her 28-year-old self. She saw her future home, her future boyfriend, and her future work life. All of this was very strange to him and very far away from him. He could see everything in the future. She went back to the past again and again, and traveled to the future again... 28-Year-old Yun Shu just saved an email, but woke up the next morning and traveled ten years ago. To him, everything was like a dream, everything was exactly the same as before... Because Yun Shu took the initiative to get to know her future boyfriend Zhang Zinan after traveling through time, she fell in love with him more and more after spending some time with him. Yun Shu traveled through the future again and found that she had done something very strange even if she traveled to the future. She would ask Zhang Zinan the next time she traveled through the future. None of her colleagues or friends would remember it. Yun Shu traveled through the world for the third time and started to dream. In the dream, she and Zhang Zinan drowned. Yun Shu felt very scared. She was afraid that this would really happen. She wanted to change everything when she went back. The 28-year-old heroine found that no matter what he did when he went back to the past, he could not change what happened in the future. Even if she went back to 18 and met Zhang Zinan in advance, when she returned to 28, Zhang Zinan would not remember that they met at that time. Not only that, but she traveled to the past, what she did last time, and they would not remember the next time she traveled back to the past, but the past changed during her third time. The peaceful life was broken by time travel. While Yun Shu was still exploring, Zhang Zinan was killed. Yun Shu was extremely sad. She found that time travel could not be done because time travel would consume her body and the time of travel became shorter. Yun Shu deleted all emails and sent them again before she could go back to the past. She only had a very short time. She communicated with her 18-year-old self and wanted to change history. Can they change their destiny if they work together? Concept: suspense
