and lulz really huh~~^^
yeah, things like this happen, even in me, some of my friends here in dA, it kinda sucks seeing that you've got some brilliant idea goin' on, then only to find out some time later that an anime already existed having similarities to your own work.
things like this, we juz have to deal with it.
BUT as for me, I say you've got this one very much brilliant, with or without watching KillMeBaby, you've got the humor and plot elements goin very much well~~~^^
hence, don't let this similarity bother you much~~^^
and continue what you do best on this story you have~~~~
