I think it is maki's picture from the way he reacted to it. Plus in the extra chapter where the other guy meets maki gor the first time looks exactly like the setting of that picture. It was never addressed to seme but ig its safe to assume they probably talked abt it off screen.
Yeah I know he was in the pic, it's literary show to us. I was just only wondering if Tensei knew
Oh sorry abt that, my dyslexic ass read the first line as "IS maki in the picture" instead of "maki IS in the picture", so i thought you were asking instead of stating.
Okay so Maki IS the in the picture on Tensei's wall, but did they ever talk about it? Like is Tensei still in the dark about that? Or maybe I just missed it lol
