As for other unrequited love anime....
5 Centimeters Per Second (though it doesn't seem like it in the first section)
Voices of a Distant Star
Full Moon wo Sagashite
Honey and Clover (some of them do work out in the end)
Ocean Waves
Saiunkoku Monogatari (not only do the main characters have a bit of one, but so do most of the secondaries. Some work out in the end but it takes a long time to get there)
Rumbling Hearts
School Rumble
Fushigi Yuugi (even after when the main couple becomes clear there's a lot of unrequited feelings for the girl)
Maison Ikkoku (older anime but has tons of unrequited loves)
Black Cat (shockingly for a shounen action it has a lot of it)
