Yup, it was //SIGN. I never thought of it as slow, but then again, i might be a slow person myself. The scene where Mimiru makes Tsukasa a promise is wonderful, and the scene where Bear talks to B.T. (best character name ever) while lying down on her lap is heartbreaking. Guess it shall be one of my favorite series for a long time... Too bad the characters from that series, Mimiru especially, are just fiction...
I once thought we were intrinsically valuable. Then i found out that our values fluctuate, as though we're all part of a social stock market...
No wonder i liked that series. Nearly all characters are ideal people... Strange... Somebody's just said 'teardrops, i love you'... I wonder why Kirakishou whispered that in my ear...
As for its ending, there are two of them. The first one is marvellous, though i never understood what was meant with the lovers never managing to reach out to each other. The SP ending is horrible and i'm not even sure if it's canon; too much of a happy ending.
--edit--
Endless eight made me feel like killing the producers.
