It would be a crazy twist if the whole "people die if you touch them" thing is just the duke being crazy and finding an excuse for why Alice never touches him, because she isn't real.

I think the only evidence that she can touch him is from a few flashbacks to when they were kids, and it's never made clear if this is before or after he was cursed, meaning she may not be immune.
I do wonder how often alice does go to touch him. Scary thought to do. Whats worse when walking with people and they stumble and you reach out to help them on reaction.
for some reason i just asked myself "maybe if the girl meets the mc's mother something will happen?" another question woke inside me "what if the witch is actually his mother"
