Her sister's leg was disabled trying to save her, and she felt guilty throughout her life.
The emperor granted her a marriage, and she was forced to marry into Prince Jing's palace.
On the wedding night, Pei Jingyuan said, "What you owe Lan Xin, pay it back slowly."
She wanted to escape, but her sweetheart He Zhao was imprisoned by King Jing.
She wanted to tell her sister the truth, but Pei Jingyuan said: "Lan Xin knows, He Zhao will die."
Pei Jingyuan thought he was in control of the situation, but he didn't know that one day in the future he would regret what he did now.
The ending is a good ending. I think anyone who loves seriously should have a good ending.
