General, please go to war-将军请出征

The Beiming Kingdom is in danger, and the young general requests to go to war. This expedition is extremely dangerous, and life and death are uncertain. In order to protect the family bloodline, the grandmother marries a wife for the young general before he goes to war. Five years later, the young general returns triumphantly. Who is the woman in white riding on the same horse with him? He did not care who he married five years ago. She did not care who she married five years ago, either, she just wanted a place to stay. When they meet again five years later, he is no longer the young boy he was back then.
