Beneath that splendor, he is an heir to the throne who has been cast aside. To escape the royal family's relentless attempts to kill him, he volunteers to travel to the western frontier, seeking a long-term plan.

When he ascends the throne, will he be able to share the evening glow with his beloved once more...
