the title almost says it all... it would be even better if it had an unusual plot and/or violence and unique character design (and absolutely no fanservice)
If anyone knows of something like this please post up a suggestion...
You might try to check out "Now and then, Here and there".
It starts out rather slow but picks up around episode 5. It's only a 13 episode series and the story line in my opinion is rather well written. The supporting main character "LaLa Ru", really portrays complete loneliness when you finally figure out her bio by watching a few episodes.
