Ji-won, she is from Goryeo, has another name, Yuliya. To call him, they must choose a name for convenience: Ha-pyung chooses Ji-won, and Sun-woo chooses Yuliya. They are just two words, two names, with the same weight. The world draws a line between them and calls them different names, but Ji-won and Yuliya, along with their friend Ha-neung, cross the borders of their Korean village, between Ji-won and Yuliya.
