...i can't understand this story..anyway,i still like it...
It isn't really a narrative. Stories like Sasameki Koto, Girlfriends, Notes-- they all have a beginning, middle, and end.
This does not. These are just individual stories, about individual pairs of girls, that sometimes happen to overlap with each other.
But I hope the couples get together in the end. Kishi needs to draw a sex scene or two...
