I wonder who will be seme and who will be uke though. They're both seme material xD

I think toji would likely be the top and the black haired mc bottom , cause it seems like it , if it’s the contrary i would be really surprised but it Ill be good as well

That's true, but he's taller than the dad tough and more "bara" so I'm not sure.
Maybe they'll be seke. There was another couple like that in another work of this author
