Who knows a great romantic yuri manga/anime?

I'm looking for a new one to read or watch. I want one that's romantic but not cliche, and preferrably takes place in middle/high school.

The only one I've read so far is Girlfriends. And I've seen some of Strawberry Panic, but it wasn't really my type. I'm willing to start watching it again though if a lot of you guys reccomend it though.
