maybe the Mangaka lost interest in the Story...

I think the Story had much more potential and seemed really rushed at the ending, especialy the sex-scene was very very rushed. and is it just me or does the art, in the last chapter seem a little slipped too? It´s not bad, but somehow a little off, like it was done quickly and halfheartedly, the charakters dont look quite like themselve sometimes and the anatomy is off a lttle. Still think it´s a nice Manga, but it could have been done even better...
