On July 26, 2021, Teruo Saeki (played by Sosuke Ikematsu) celebrated his 34th birthday. After getting up, he watered the cactus as usual, and his body swayed with the music on the radio. Even on his birthday, as a lighting technician, he still worked as usual to illuminate every dancer on the stage. On the same day, taxi driver Ye (played by Sari Ito) drove a taxi on the night streets of Tokyo under the epidemic. On the way, Ye got off the car with the passengers and was suddenly attracted by the sound of footsteps coming from nowhere. Ye walked to the source of the sound unknowingly and saw Teruo dancing on the stage. Time goes back year after year. The movie depicts the starting point of Teruo and Ye's love and the moment they met, and "returns to the end of love" with the two.
