He fell in love with her and would like to meet her, but he could not because of the time difference. The boy learned that the girl was in a period of disaster (1923 Great Kantō earthquake) and wrote to warn her, but she did not reply after that. The girl's letter was sent to him later, described by the boy as "the last love letter". He regarded the letters as proof that girls are alive in her time and are determined to one day convey to her the experience of their own time.[12]

The music video begins with a vivid background, showing Tokito, a boy who wears contemporary clothes, and Chiyoko, a girl who wears Taishō-era kimono, reading a letter with a showy background of kimono pattern, clocks, and household electric appliances flying past behind them. Then, they read it on the street in their era, Reiwa, and Taishō. The background is changed between a modern railway carriage switch and a wood-paneled railway carriage, shown they read a letter in the end.[23]
After that, Tokito turns around to see the giant clock pointing to 11:58 in the background, which is the time that the Great Kantō earthquake occurred. Suddenly, he runs across the showy background and throws a letter into the door being close. Later, he walks crestfallenly, showing the black lyrics on white background. The door opened to show the letter is sent to Chiyoko. She read it and run to throw her reply letter sent to him. He reads the letter while standing on the hour hand of a clock and meet Chiyoko, which stands on the minute hand. Finally, the pair runs towards each other and embraces, but as quickly, the music video ended up with Chiyoko fading from an explosion of light.[23]
