trying to remember a oneshot manga about a mother with a terminal ilness that leaves a video recording of herself for her daughter to be watched by the daughter when the daughter reach a certain age and milestone in her life.
@Arantir
that premise reminds me of one episode of Violet Evergarden, though they are letters instead
also I kinda feel like have read another similar premise, but it's about man asking a flower shop to keep sending flower to his lover after his death for her birthday or something, though I don't really remember that one. I got nothing else.
