The northern city fell. The defeated were forced to send a noble young man as a hostage to the southern king. Even though they also sent a noblewoman, the southern city did not welcome them warmly. It is said that after encountering the noble young man with a face like the moon and a spirit as bright as a flame, fate began to play its games.
