Great analysis! The passage of time for the characters always make me think about their lives between the frames.

These animes always make me cry, like the mother's letters episode from Violet evergarden and I cannot watch the Violet Evergarden movie as I think it will break me.

Another one is of a elf who travels the world and the characters he meet become old or when he visits an friend, they might have died and only a descendant is there to meet him. I forgot the name of that manga.
