So, my theory is that the MC's mother is the Lady Orpheus that was mention in chapter 8. The abusive count said that the MC looked just like her. I think he meant MC's mother that he loved but was rejected by her. And I think, that is why he hates the Duke and talked shit about him to the MC, because Lady Orpheus was most likely in love with the Duke.
But this is just a theory ╮( ̄▽ ̄)╭










This explains why it felt so strange to read it. I was wondering if it was the translation but scan groups generally produce pretty good quality.
Now I know it really is just the way it is written. ╮( ̄▽ ̄)╭
