If I'd Kissed Her (2021)

A supermarket employee is happy with his job. One of his pastimes is to read manga and so is excited to meet the author of one of his favourite mangas at the supermarket shopping one day. She is a customer there. They become acquainted and become fast friends. They set out to travel to Okinawa together, but one of them does not make it. Shock is added to grief when a man claims to be the reincarnation of the dead manga writer.
