In episode 16, Lin Beixing found a book "Loneliness of Prime Numbers" in the Sea of Time and Space, which tells the story of two lonely young people, Matia and Alice, each with painful childhood trauma, trying to get close to each other in life, but constantly getting away from each other. The name "Zhang Wansen" is on the library card inside, and the production team is also very careful. The loan date is 2 1 May 20th, and the repayment date is unclear (21May 2nd1if I remember correctly).

May 20th, 2 1 year is the day when Xing Xing and Yu Zhan got engaged. If Zhang Wansen knew that they were engaged and sneaked back, the date was right (of course, it was not ruled out that it was because of work. When I was a child, my wish was to be a veterinarian without borders, matching the mobile phone number in Africa. I have a brain hole. Could this "sea of time and space" be opened by Zhang Wansen (there is a star chandelier outside the store, which may be a coincidence)?

At first, 20 10 only said that something had happened to his lighthouse, not that he was dead. The child is not "Zhang Wansen", is it? Will children read such an esoteric novel as Loneliness of Prime Numbers? What if you find Zhang Wansen, the bookstore owner, performing with children and tutors? Can a normal person see the boss at will?

Is it a coincidence that "Zhang Wansen" met a star in a certain picture? Even if I start over, Zhang Wansen will still protect her behind the stars. I have always felt that after Zhang Wansen fell off the tower, there was a reflection of a place. Don't you find it strange? Shouldn't the normal reflection be aimed at the tower? Its reflection is reversed, and its reflection is that the top of the tower is facing the top of the tower. I didn't fall into the water, I must have fallen into a wormhole. The short message of the stars can only make her return to the moment when Zhang Wansen regrets (I have traveled so many times, but I just missed one thing and watched the first snow together). Just say "I like you" and the game is over. The "rules of the game" have changed, and all the events have moved forward. Zhang Wansen's last crossing was really saved. Maybe he went abroad. He said "I like you" at the airport and the game was over.

The tenors who didn't intersect with Yang Chaoyang before all came back to reality, so the final crossing changed. Although it ended in an open ending, I believe that it was Zhang Wansen who held an umbrella for the stars in the first snow in 2022 (unfortunately, I just watched the first snow together). Without si, I don't know if you have noticed the credits at the beginning of the film. Finally, someone held an umbrella for Lin Beixing!
