The artist is yamane ayano, but I've heard that's not a manga but just an artwork.

I think it's this one. The seme has long, wavy hair.. He's also a king, hence the fancy outfits and bed.

I don't know for sure, though. In this manga the seme has blonde hair and the uke has black hair. But it's close enough, right? :)) give it a read

I know for sure it is not a manga but an artwork from Ayano Yamane... Just like Loli said.
