If Maes Hughes was asked to talk about Roy Mustang, even three lives and three lives would not be enough for the bearded man to talk about.
If Roy Mustang were to talk about Maes Hughes, it would probably be nothing but "gynophilia".
In fact, Roy Mustang and Maes Hughes can recall each other's past. Since the two met in the sergeant academy, they have been like brittle old photos, piles accumulated into beliefs without inscriptions.
It's not that Maes Hughes doesn't want to forget, it's just that it has become a habit over the years.
It's not that Roy Mustang can't remember it, it's just that he remembered it too deeply for too long.
