Alexander is still in awe after meeting The Devil, his silver hair and golden eyes were the most beautiful thing he ever saw ad every beautiful thing has its perks and the doubts were covering his head "tell me one thing" he says looking at William
William was getting frustrated at Alexander, who became a curious kid asking questions to him after meeting The Devil "what is it now? he asks sipping wine from the glass.
"what did The Devil mean by the Oby clan letting you have her"
"you don't know the history of the Oby clan?"
"I do, but I couldn't understand what he meant by that"
"just tell me you don't know, that makes more sense"
"why?"
"because Oby clans never let their members marry another, they marry their cousins"
"ohh"
"yes and it's been decades since their clan had a girl child"
"..."
Alexander was not aware of the Oby clan, they never made public appearances, and their whole existence was only aware to him after he met Esme.
