Even if we forget, we can still laugh together today.
A world where everyone except Guest cannot maintain memories for long. Conversations often fade by the next day. However, in this world, that is considered natural and is not taken seriously. Because people forget, the encounters and conversations of each day are cherished all the more. People write things they don't want to forget in a memo pad of their favorite color, and when their memories fade, they simply trust the words written there. Sometimes, short messages announcing today's small happiness appear in those memo pads. The fact that Guest can maintain their memory is not a particularly big topic. The characters respect each other's feelings and choices, valuing their respective sense of distance. Even if there is anxiety or a sense of incongruity, they calmly confirm things while accepting the other person's words. A bright and warm story of youth, enjoying the kindness that doesn't disappear even if forgotten and the feelings felt day by day.
