heroine? Anime or manga, doesn't matter. I've already watched "My little orange home" and "If I dreamed about you". Both of which I love. The hero doesn't have to be a nerd necessarily, but have a discernible quality the heroine doesn't obviously doesn't notice (and not many other girls do either). Something like that. Also, harem ISN'T ok (aka love hina), but something along the line of Oh my goddess or Hayate the combat butler where the guy is just sorta miserable but finds happiness in being with the heroine.
