Bodyguard by Your Side: General, Please Behave

In the twenty-first century, Cen Miao transmigrates onto a battlefield and is mistaken for a spy. General Cui Yan saves her, and with nowhere else to go, she becomes a servant in his estate. When others frame her, Cui Yan gives her a brutal beating. She remembers it all... and vows to get revenge! When my hair reaches my waist, will you return, General? I had hoped to roam freely with a noble heart, never imagining the land would be so bleak. We met at dawn's first light, and grew old together beneath the evening snow. A cold sword silently hears the thunder, while a long spear guards an empty trench alone. Don't laugh at those who lie drunk on the battlefield; all night, the horns' mournful notes ring out. When your hair reaches your waist, I will return victorious to court. Once I rode wherever I pleased, a young hero, fearless and bold. The rosy clouds of the eastern capital are beautiful, while West Lake stretches hazy beneath the mist. I fought with my spear against foes on every side, swearing to protect this splendid land. One day I will return victorious, and spend a beautiful night with you.
