Sugufushi- would be soft. Megumi would frown everytime they encounter each other. Growling at him which sounds like a hiss to suguru. He of course knows he's not an alpha. But he plays along. Cleans his wounds and puts bandages on him and tells him "get hurt less next time" instead of telling him to stop fighting. They slowly grow closer and maybe megumi ends up telling him but suguru just laughs and says he knew already.

Yutafushi- I think yuta would be a slay mf. He would throw taunts here and there and make stupid jokes but he wouldn't let anyone hurt megumi. He would beat up anyone who would pick a fight with him but in front of megumi he would act like he don't give a damn.

Gofushi- gojo would definitely be the asshole. He would ask megumi why don't he shower with them after sports or tell him to come have drinks with the alphas. But since megumi is so stubborn, he would end up losing it and forcing him to submit.
