Everyone in Beisheng knew that He Yunchao was the "General of Valiant Cavalry" personally named by the emperor. Everyone in Beisheng knew that He Yunchao was a woman! Everyone in the palace knew that Gao Yu was a useless prince, but everyone in the palace also knew that this useless prince was being protected by He Yunchao.
He Yunchao: Everyone says that I am protecting you, but in fact they don't know that it was me who was always being protected.
Gao Yu: It doesn't matter who protects whom. What matters is that we can protect each other.
Like Yan on Liang, I wish to see each other every year.
Purpose: support and progress together
