What are some anime shows like Sora no Otoshimono Forte?

well i think that Chobits a href="http://myanimelist.net/anime/59/Chobits" rel="nofollow"http://myanimelist.net/anime/59/Chobits/a and DearS a href="http://myanimelist.net/anime/63/DearS" rel="nofollow"http://myanimelist.net/anime/63/DearS/a have pretty much the same base story of Sora no Otoshimono
