The opening animation looks pretty cute, as do the girls of course. It looks to be a slice-of-life high school romance, and let me say that the girls do have cute designs. Here they are-- the descriptions are based on their designs and voice samples (available on the official site), so they could be a bit off.
Yu Kawamura - The main heroine. Cute as a button. I think I'd like her better if her voice samples didn't sound like they belonged in Hanamaru Kindergarten.
Aya Kagura - I think my favorite so far, she's a bit more rambunctious than Yu. She also seems like she might be a bit of a troublemaker (one of her clips: "It's okay, it's okay, it'll be fine from here," the kind of thing frequently said by a character trying to get someone else to do something silly).
Mana Miyuki - A meganekko, but not your standard shy type. She's a bit cold and easily irritated, probably a tsundere.
Nozomi Akiyama - Her voice sounds like Rie Kugimiya's (it's not, though), but she seems like less of a tsundere and more the type of girl who's a little bit oblivious and speaks her mind.
Izumi Shizuno: A Nice Girl who speaks a bit formally (at least at first). The super-nice, friendly, responsible one, I'm guessing.
I don't normally get around to playing many visual novels (it's hard enough for me to find time to play my mainstream games), but for free? I bet I could find some time. How about you?

























Also, in waaay before anyone downloads it, plays, and 'demands their money back.'
I suppose being free isn't half bad either. :)
Edit: Only thing about Yu's voice...
is this going to be another show like Shuffle?
@haseo_yashimora: Yeah, I like Yu's design (especially the hairpiece) but man, she sounds like a five-year-old even by anime standards >_>
