Coming of age “unrequited love” movie recommendations?

Almost ladybird-esque.

I’ve looked through some threads and recommendations on google and on here but a lot of them miss the unrequited trope. “Unrequited love” as in they don’t end up together in the end. As said, ladybird is one of my favourite examples I can think of. Coming of age movies are one of my favourite genres and this trope makes it so bittersweet to me and it’s something I haven’t seen in alot of movies before. The entire plot of the movie doesn’t necessarily have to revolve around the romance, but it can and I’d be fine with something like that!
