I haven't read the raws but based on my fujoshi's theory, that black hair guy is an uke.
I really love when a strong guy becomes a uke for his seme. It makes me feel that the uke really really loves his seme in his own way HAHA XD
Usually the gap moe character will become an uke
YES IM SO SURE THE BLACK ONE IS UKE
MMMMMMMMOOOOOOOOOEEEEEEEEEEE!!!!!!!

He did kinda give off an uke vibe when Yoshimura almost kissed him in the kitchen when they were baking and again at the end when they kissed.
I hope it’s not just me but I actually wanted the black hair dude to be uke.. hahaha idk I think he’ll be super hot as a uke
