A Smile Follows the Song: Moon Over the Frontier Pass

After falling off a cliff and losing my memory, a rival prince wanted to imprison me, while an old flame, a prince himself, wanted to deceive me. Then I came across the reclusive master Xie Yun Yuan. He healed my wounds, taught me strategy, and helped me crush my enemies and turn the tables. Together, we would rule the realm. This world, it turned out, was the grandest betrothal gift he could give me.
