I like it, but I'm kinda lost. Like, did the original Stuart family die too? From food poisoning? They died at the same time, that how they "overlapped"? But since they seem to also have BOTH memories, when the little one talks about "forgetting about the bugs" while Emma was in bed after the food poisoning... Did the original William forget, not the reincarnated one?
I feel it's just an issue of cramming/skipping a bit too much in the manga compared to the novel...
