Only Yesterday (1991) IMDb
An adult woman remembers the aspirations and adventures of her childhood, and tries to decide what to do with her life. Has she been putting on a happy face and following a normal career because it is expected?
Mundane parallel plots separated by 16 years. Introspective romance? Is understatement a genre? There are two scenes in this that would have looked a little odd in a live-action version. Low-key stuff, and wonderful.
