Lee, Shin

Crown prince or "Taeja-Jeonha" of Korea. He is portrayed in the beginning as arrogant and insensitive. Pressured to marry early, he accepts the choice his father and the elders give him (Chae-Gyeong) after being rejected by his girlfriend Hyorin.

[Spoiler] Shin later shows that Chae-Gyeong is the only one that is really close to him. He also doesn't want to let her go. [/Spoiler]
