Song Yinghe, the daughter of Marquis Liang, never thought about returning home from the moment she disguised herself as a man and traveled to the Liang Kingdom at the age of twelve. However, under a marriage agreement, she was accused of being married to Marquis Chang, and she also met someone outside the trap. From being in the spotlight to falling into the dust, she had only one thought: to survive. She was dormant in the wilderness, with a stiff body and long sleeves, and was good at dancing. She went through all kinds of hardships just to rush to her enemy thousands of miles away and say to him: "Ming Xin, I'm here to take your life."
At the end of the red line that is hard to reach, she is destined to walk alone, for her father and for revenge.
