I absolutely adored reading this and I was happy with the ending. The only constructive criticism I can think of is more detail but that would only really be if you decided to make it more than a oneshot. It was a PERFECT oneshot, though more reasoning would've been awesome! It would make an amazing story as well.

i was going to make this more, but i thought it would be better as a one shot as if i added more it would drag attention away from the point i wanted to get across. i also wouldnt know where to take it without it getting run-down and boring. ox.
