Plot hole? Or did I miss something? ('My name is ... Mio?') SPOILER
Hi,
When Yuji and Takumi find Mio in the forest, she apparently doesn't have any memory of her own name or of Takumi. If, as it turns out in the solution, this was her 20-year-old self, which made a "time jump" into the future, she should know both her name and and her classmate Takumi, right?
Well, maybe I'm just too rationalistic in analysing this beautiful movie...
