I recently re-read the entire AnY manga, twice, and there's still just one thing I'm a little confused about... Soo Won's mother, Yong Hi.
The memoir Yona reads seems pretty well like her last words and gives me the impression that she passed away very shortly after writing it. But, before the discovery of the memoir, someone (was it Min Soo?) tells Yona that Yong Hi is resting in a villa far away for her health.
So, is Yong Hi dead? Why bother lying about it? My first thought was that Soo Won wants to hide the illness, but it's already common knowledge that her health is poor.
