noopee. not the same
i only remember it as a yaoi manga with high achool Studnets and the bottom i think was some nerdy with curly blonde hair and he was like all cute and innocent but actually dominant and he like dubconned the seme by riding him i think the seme was like a jock idk. uke is small and has significant size gap with seme
