Hey guys, loved the reaction as always!
So, regarding the demon backstory, I think it is ok to not sympathize nor to feel connected to it. I have always seen it as them showing that, so we understand that it was not really the little boy’s choice to become like that and to eat his own brother. When the humans become demons, they lose their senses and control. Also, they lose their memories as humans. So, the little boy actually forgot about his brother, only remembered when he was dying. I think the point is to show that, even if they killed a lot as demons, they were once humans and it is the human I sympathize with, not the demon version. I "feel bad" for what the human became, because it was not his choice or wish.
Regarding Nezuko, the fact that she can sleep instead of eating humans is something new that has never happened, she is not like other demons. For others that is not a possibility. Also, she was asleep for two whole years, that was the time Tanjiro was training before going to the Final Selection.
I'm excited to see the next episode reaction, I will request next month for sure. Thank you!
