Who is the man with the glasses in the last page

and also the one who is above him?

I think the man with the glasses is the ml from https://www.mangago.zone/read-manga/the_princess_pretends_to_be_crazy/ just because of the glasses? lol

and according to some comment I've read the guy above is a novel cover of https://www.mangago.zone/read-manga/omniscient_reader_s_viewpoint/
