What story where the guy doesnt get the girl?

Name me an anime storyline where the guy doesnt get the girl he ultimately desires? Not because of like she died or they are far apart but just because the girl in the end just doesnt love him?

Off the top of my head, I though Eva was a candidate. Since shinji technically had feelings for Asuka but never got her as such.

Voices from a distant star was pretty good, but apparently he wrote a text sequel that ruined it.
The guy went into space and met up with her, because she had been rescued. And the travel meant that they were happily the same age again.
