Kon'nichiua! I'm kinda looking for a shounen-ai/yaoi manga that is kinda long but with kin...

Try Genwaku no Kodou - the art is a little old school, but the story is great

Shounen-ai: Koori no Mamono no Monogatari and Komatta Toki ni wa Hoshi ni Kike (I didn't read it yet but a lot people like)
Yaoi: Haru wo daite ita, Ze (I didn't read it yet too but a lot people like) and if you don't mind ongoing there is Honto yajuu (I know there is saying there are only 18 chapters, but if you count, there are more).
