MC will have to unite force with an isekai'd otaku from his same world?, and form a pair, this opens the possibility to form a romance with what he think is the lowest class
My bet is that mc will be mind broken and will be forced to satisfy male commoners in karma of her past self actions. maybe even get paired with a ugly bastard.
Paril is putting a lot of effort to become the successor but for some reason I get the felling that she will be unlucky and her new sibbling will be a little brother who will take the successor title from her
Oh please don't close his arc now, let him have a chance in the future, but I will understand if this makes him realize about what he really wants in the future and what he can do.
