Some stories gradually draw you in. You grow deeper without realizing it, you cling without realizing it, and in the end you feel like something has been taken away from you. Japanese director Shinichiro Ushijima's 2018 animated film offers exactly this kind of experience. The story begins with what appears to be an ordinary coincidence: a diary that falls into the wrong hands at the hospital. But this diary opens the door to a completely different world for the introverted young man who finds it. Sakura, the owner of the diary, is full of life, has a smiling face, and possesses an attractive personality. The secret it carries forms a tragic contrast with this painting. The most heartbreaking aspect of the film lies right here: Sakura's deep, almost tenacious bond with life makes the shadow of death even sharper. The distinct personalities of the two characters form the backbone of the film. On one side, Sakura, who clings tightly to life and wants to cherish every moment; on the other side, the nameless narrator, withdrawn from the world and keeping people at a distance. The gradual closing of the distance between these two characters both fills the audience with hope and makes them uneasy. Because you can't help but wonder where this closeness will lead. Visually, the film successfully utilizes the mature and restrained palette of Japanese animation. The warmth of ordinary days, school corridors, lunch breaks, and short journeys—all conveyed with nostalgic tenderness. The music, on the other hand, quietly settles beneath these images, seeping in without making any noise. Adapted from a web novel, this story neither slips into melodrama nor into cold existentialism when dealing with the theme of death. Instead, it asks what it means to live and how being with another person transforms one's life. The answers are not clear, and the film does not attempt to provide this clarity. Accepting uncertainty, and even holding on to something despite it, seems to be the film's central theme. This is one of those films that stays in your mind for a long time after watching it, and when you think about a scene from it, you find yourself rewinding to the beginning. Sakura's "to-do list" might just inspire you to write your own.
