Ye Zhaoyun is a princess of the Ye Kingdom. She learned martial arts from her mother from a young age and became highly skilled, but she didn't want to spend her whole life cooped up behind palace walls. After informing her father, the emperor, she ran off to a small town on the frontier.
Traveling under the assumed name Yun Zhao, she hid her martial arts skills and pretended to be a delicate young woman. There, she met Shen Che, who was likewise pretending to be a young master of an escort agency.
War broke out on the border. When she heard that the general who protected the country was gravely wounded, she hurried back to the capital and went to war alongside her elder brother.
She donned armor, tied up her long hair, dressed as a man, and led the troops to the front lines.
When she reached the battlefield and faced the opposing general, she froze.
Whatever happened to the young master of the escort agency? How did he become a general of the enemy kingdom?
She wasn't the only one stunned. Shen Che was just as bewildered.
Why did the opposing general look exactly like the delicate young woman he knew?!
The two stared at each other in silence. The soldiers behind them stood still, waiting for orders.
"Do you... know a woman named Yun Zhao?" After a long standoff, Shen Che spoke first.
"You know my little sister?" She wasn't about to admit she was Yun Zhao.
They exchanged a glance, then gave the order to attack at the same time.
When the war ended, the two kingdoms formed an alliance.
Shen Che entered the capital with the diplomatic delegation, but didn't see her. He asked around for the whereabouts of General Yun, the woman he'd seen on the battlefield.
The officials had been warned by her and didn't dare say a word. He couldn't find out anything.
He went back to the small frontier town and saw her again. He volunteered that he was a general of the Xiao Kingdom. She wasn't surprised and told him she'd heard about it from her elder brother.
At the border between the two kingdoms, soldiers from the Qi Kingdom were killing innocent civilians.
Her residence was close by, so she sent word back and volunteered to go deal with it.
The Xiao Kingdom also sent Shen Che.
When they met, they stared at each other in disbelief.
Oh, no. She wasn't dressed as a man.
"My elder brother is tied up with something, so he asked me to come see how things are going. He'll be here in a couple of days." Wow, he believed her.
After the matter was settled, the emperor heard gossip from his officials and summoned Shen Che to the capital. He asked whether Shen Che would be willing to marry the princess if he arranged the match.
Shen Che refused. He didn't want to marry a princess. He was in love with the girl from the small frontier town.
The emperor was stunned by that. Good grief, the man still didn't know she was the princess?
