Story: 8/10
Rather than a "story", this series is full of stories (at least from the 3 eps that I've watched). Each episode comes with a different story. But they all have the same theme: Love & Relationship. The varying ages of the characters make it possible to explore love and relationship from different views, that's what make this series special.
Art: 6/10
The art isn't anything grand or cute like your typical shoujo romances. But I find the art quite fits the overall mood and atmosphere they're trying to create.
Sound: 8/10
The soundtracks really helped to create the mood. I especially love the whispering voices of the character's inner thoughts.
Character: 8/10
It not a series which focused in the characters development. I mean, it's only 3 minutes per episode. But in that short time in 3 minutes they're able to make us sympathize with the characters. All these characters has flaws. There's not a single "mary sue" character, which for me is a big plus point.
Overall Enjoyment: 10/10
I pretty much enjoyed it, and I'm fully aware that giving a 10 score is maybe a bit too much, and I might change my opinion later.
EDIT: I turned down the score to 8.
