At first, Lin Beixing thought that the opportunity to travel through time and space was to delete the past short messages, but with the development of the plot, Lin Beixing was sent back to her original time and space again and again. At this time, she realized that she could go back to the past only because Zhang Wansen had regrets, and when all the regrets were completed, she couldn't go back.
Similarly, Lin Beixing initially thought that she was sent back to the original time and space because of Zhang Wansen's death, but when she crossed back to the college entrance examination that day and saw Zhang Wansen tell him that I like you, she immediately returned to the present. At this time, she realized that the original crossing node has always been that I like you.
No matter who said that, Lin Beixing will be sent back to the present. I have never seen Zhang Wansen in Lin Beixing's life, but Zhang Wansen's life is all about him.
Zhang Wansen once loved Lin Beixing for more than ten years:
Zhang Wansen loved Lin Beixing silently for more than ten years, and tried to get close to her again and again, but she never got Lin Beixing's concern. I tried to change again and again for Lin Beixing, and I made mistakes again and again. But his love will never turn into jealousy, intolerance or resentment because of love. He loves her, protects her, and hopes her well.
Therefore, when Lin Beixing's mind was focused on the campus boy Yu Zhan, Zhang Wansen's loss was real, but what he wanted was to help Lin Beixing sort out his notes and realize his dream of going to Beijing to go to college with Yu Zhan. In the youth stories of Zhang Wansen and Lin Beixing, the most important emotional point is undoubtedly recognition and protection.
