She didn't know that this domineering and willful "princess" was the only prince of Qi Kingdom.
She discussed life-long events with him. She was going to leave the palace to get married, and what kind of consort Chang Ning should choose.
She didn't know that in the dead of night, he looked at her sleeping profile through the curtains and said something silently.
"I don't want a consort, I just want you."
Later, Changning resumed men's clothing and became the prince.
Yue Chuyun traveled far away to the end of the world, running towards her fiancé,
Later, Qi Guo's cavalry broke through the Thirteen Borders of Mobei
On the day when the army arrived at the city, the prince, dressed in black armor, stretched out his hand to her.
"Tsuki Izumo, how long are you going to escape?"
"You used to think of me as your sister, but now... I'll show you who I am to you.
