Saiki Kusuo likes Aiura Mikoto. Touma knows, even when not even Kusuo himself does, probably. He's mostly sure of it. That Saiki doesn't know, not about him liking her. He's sure of that. The same way he's sure most of his classmates find him annoying for talking so much, all the time, and for knowing things that he shouldn't be able to know. Akechi Touma-centric. But not really. I'm not even sure. Sorry.
