Remember what scene Wei Zi first called Yong Qi's brother, and what was the purpose of Wei Zi?

Speaking of Princess Zhu Huan, everyone is familiar with it. Many childhood memories after 80.90 must be Princess Zhu Huan. Speaking of Wei Zi and Yong Qi in this drama, although they are brother and sister, their feelings are not very deep, because Yong Qi grew up in the palace and lived a luxurious life, while Wei Zi was away from his father when he was a child, and finally his mother left when he grew up, so these two people just lived in two different worlds.

The first time she called Yongqi's brother, it was because Xiao Jian returned to the Qing Dynasty from Myanmar and told everyone that Erkang might not be dead, but was just imprisoned. So both Wei Zi and Yongqi wanted to save Erkang, but the emperor didn't agree. Wei Zi still wants to save Er Kang secretly, but she thinks a woman is too weak. At this time, Yongqi spoke her true thoughts. It turned out that he and Wei Zi thought the same thing. He also wanted to save Erkang and made a plan.

When Wei Zi heard Yong Qi say this, she was very moved. After Yongqi finished, she began to praise Yongqi all the time, saying that he is the best person in the world and the best brother in the world. This is the first time she called Yongqi's brother, and when she called Yongqi's brother, her eyes were full of admiration and more gratitude, because she hoped Erkang would go home as soon as possible.

So I think Wei Zi called him brother because of Erkang, because all she could think about was how to save Erkang, and she was so excited that she didn't know what to say. I don't think she really called him brother.
