@uMoonlight @Pocky8 I've noticed a few of the male characters have similar faces. It could be a case of "same face syndrome" where the artist gives very little variation between faces.
I haven't read the novel, so I don't know what will happen, but I have wondered if Oscar is somehow related to the imperial family because he does look a lot like Cesar and he has red eyes like the Emperor. Again, it could be "same face syndrome," but some of his comments in the past have led me to suspect this, and Canaria thought he looked like someone she knew. I don't want any spoilers, though.
