Dont worry rihito is gonna teach her how to cook, by that i mean putting some buns in her menhera ovenOne step forward, two steps back.
Starting to wonder if Noa's mental issues might actually come from a lack of divertive focus for an overactive brain and lack of fundamental REM sleep...
If she finds a hobby that does enough to drain out that mental energy and gets proper sleep, she might be a lot more emotionally stable and... 'normal'...
In short, Rihito's screwed. Cause that ain't happening, especially not in this series.
