I'm really glad that Noahs "I'm Astras wife" is handled like this... Like a normal kid who wants to marry her parent/kindergarden teacher
and not like some weird Loli stuff. It feels like forever since I last saw things developing like this in a manga...
Well it kinda always weirdly shined through that she was older. Hardly any peasant child would request a teacher for reading out of the blue, since they would not know the importance of being able to read (especially someone who spent half her childhood in a box). There were also other instances...
