Visionary the Other Side

From DramaQueen:
In a small kingdom where chivalry exists and heroes are living legends, an extraordinary adventure awaits a young princess--Nan-Fan, Princess of Tang: young, na?ve, and strong willed.
On the eve of her arranged political marriage to the brutal "Battle Demon" of the rival Li Kingdom, she escapes from the imperial palace to seek her true fate. On this journey, she begins to understand the joys and hardships of the common people and realizes that living outside the palace can teach a young princess how to become a person of strength and character.
Thus, undaunted by the unknown, Princess Nan-Fan forges ahead, reshaping the myths and legends of her own destiny.
