Blue Birthday (2023)

My Blue Birthday (1x10)

:

Karin, in the past, dies in order to save Jun once again. He, Yuto, Mayuki, and Yohei grieve deeply. Jun, however, then remembers that the film contains twenty-four shots, but if the camera is set up correctly, it can go up to twenty-five. This means that there must be another picture left in the camera that hasn't been developed. With this hope, Jun goes back in time to save Karin.
