Love Monster? that's the first time i've ever seen that referenced....at all...
it was a pretty good end I guess...shame it's over now.>>13033228
also for OP try out Gantz, it's all about this boy who's trying to find the right girl but when he does his old pal from gradeschool whom he met recently up and steals her from him.
also I think there's some kind of side plot about a fight or something that they have to do, I dunno, I dont pay attention much to it.
