I think the story captures the feel of youth beautifully. It works very well as a short, just like Aoshima's short impactful days with Minadzuki before her transfer.
Not to mention how the mangaka drew those pages when Aoshima notices how Minadzuki sees the world through her paintings. Pretty awesome....
This has got to be the funniest, cutest, unsexy sexy "almost" sex scene I've ever read!!!!
