It seems that at some point, a good person will appear in front of me. He knows me, and I know him... Japanese science fiction classic, the earliest "time travel" novel; the original work of the animated film "The Girl Who Leapt Through Time" directed by Mamoru Hosoda, which won the Japan Academy Award for Best Animation Award and the Tokyo Animation Festival Best Animation Award; it has been adapted into 4 movies, 4 TV series, and 4 comics in the 40 years since its publication. After school, there was a sound of breaking glass in the science laboratory. The liquid flowing out of the broken test tube was slightly steaming, exuding the sweet fragrance of lavender. Kazuko Yoshiyama, a third-year junior high school girl who was cleaning the laboratory, suddenly fell into a trance. A strong sweet fragrance suddenly hit her, making her stagger uncontrollably, and then slowly collapsed to the ground. When she opened her eyes again, the things around her, time and memory had all undergone wonderful changes. Under the sudden impact, she would travel back and forth in the time tunnel, and she even met a boy from the future. Unbelievable things happened one after another.
