@Galder: I guess whoever tagged it as "School Life" felt it was redundant to put in the "Slice of Life" tag. That's the reason it's, as you put it, "All over the place." School Life is the same as Slice of Life only in a school setting (and I question this further considering we've only focused on the school setting at best 1/3 of the manga. Slice of Life makes more sense, personally). Feels like false advertising, doesn't it?
But yeah, I agree with your summary. It's a good read, kinda ecchi, definitely SoL, but not heavy in story.
