I have the same opinion as Moon, I think it would take a lot of the weight off Akira's past, Akira is very broken because of what Sekai did to him...... shit, when I started writing this here I thought of something, Akira involuntarily hides other guys, wouldn't that also be an indication of his trauma with his brother? Like, he doesn't hide the girls because he believes that Sekai's relationship with him was love, but with Nozomu he's angry, scared and that's why he hides other guys and not just out of jealousy? So much so that we know that Akira Prime really didn't get along with the other guys who work at the school.
