yaoi mangas rule is ([uke must be older manly /seme must be younger small cute manly] ) any thing like Kawaii Akuma
Otona Keikenchi
Bousou Kareshi
Dame na Kurai ga Choudoii
Jive
Giocatore, Hokaku Keikaku
Love Neko........... anything new

So , you can try this :

I got a lot of ideas from there 🙂

Also :

A lot of [MISHIMA Kazuhiko] 's works ( the mangaka of Love Neko):
Puchi Puri ( definitely , although is more shounen-ai...but cute, nevertheless 😛 )
Papa I Love You
Oyaji Hiroimashita well, the seme isn't soooo cute like the one from Kawaii Akuna, but still he's a lot younger then the uke, very spoiled and very cheeky, so this one is worth reading 😛 )
Miwaku no Ringo ...a good one !

Short story 7 of Hounetsu Jive a MUST!! the seme is not only cute, but also very devilish ...and the uke is a "japanese punk " 😛 😛 ( the ones the you can sometimes see loitering around in mangas)

Ore no Tenshi wa Mayonaka Akuma ...i think..
