One Second Ahead, One Second Behind (2023)

Hajime, who works at a post office counter in Kyoto, does everything at a faster pace than most people. One day, he meets Sakurako, a street musician, and falls in love with her due to her singing voice. Although he manages to arrange a date at the fireworks festival, when he wakes up, it’s somehow the next day. Eventually, Hajime learns that Reika, a slow-tempo college student who comes to the post office every day, holds the key to the “vanished day.”
