Also a bit curious about the age thing.
In the first chapter Canaria does say that both she and Cesar are 12. This new chapter says they are now 17. So why does she say "Well not friendlier as a married couple... but as a 10 year long male friend?"
They haven't known each other for ten years, right? If I remember correctly, in the second chapter she makes mention of "My 'new' parents who did not hesitate to sell their 12 year old daughter..." so wouldn't that mean they only knew each other for five years? I don't know any Korean whatsoever so I'm just curious if the "10 year long male friend" was mistranslated.
