i really want to find yaoi manga like elektel delusion which the seme is cute but cool and the uke is more gentle than seme with school life background.

Otona Keikenchi is the prequel for Elektel Delusion.. so, just in case you haven't read it..
anyways try Uwasa no Oujisama the first story, (the seme is definitely not cool but more of a cry baby xD)
and maybe Calorie ?
that's all i can think of right now. ^.^
