Who is the old woman? Is she a human or Ancient Korea?
//She, my dear anonny, is the previous dynasty of Korea before it became "The Republic of South Korea". The dynasty was named Joseon, which was the longest dynasty compared to other periods (I wish I could name them but they have to be in Korean XDD;;;)
I thought, "Hey, if cities can become personified... and the Roman Empire and whatnot can be personified... why not the dynasties too?" So I created Joseon~ >v<
But since Joseon was was dissolved by the Japanese, Joseon slowly began to lose her standing as a dynasty. She began to age. It was very slow at first, but she became fully human after a few decades "The Republic of South Korea" was made.
Now she's their mom. Although YongSoo's practically older than her, he just calls her that because it seems appropriate to him.
