I only mean for the few first chapters. I wouldn't want to be spoiled.

For example, does Yuuichi meet Ayu and then (major spoiler for original work)

freak out that she's not "dead"?

umm well ...
yuuichi here seems know everything, like the last chapter released, he can see far distance ... ups, its not spoiler right?

I like it though, with different yuuichi from the original, its fun to read
*well yuuichi original kanon is a type that you can find many anime,yuuichi at wonderthree is unique one" 😀

ah, and I think ayu not the main heroine in this wonderthree
'cause her story end at first few chapters xD
looking forward to nayuki action
