Can somebody give me some manga where the seme is cute looking and smaller than uke? thank...

http://www.mangago.me/read-manga/boku_no_high_spec_kareshi_sama/ i didn't like it, but maybe you will xD

I have a "Shorter seme" list http://www.mangago.me/home/mangalist/59917/
most fitting: 2, 4, 9, 13

kawaii akuma series ~ <3 to find the other sequel just look at the author's works
