Maybe Yun Xiyang once fell in love with Yecheng, at the moment when he helped him drive away snakes.
Regarding the origin of the name Yun Xiyang, she said this: My mother was uneducated. When I was born, the sun just set, so my mother named me Xiyang. She had no surname, but I couldn't. She looked at the clouds in the sky and asked me to take the surname Yun.
Yun Xiyang: Little beggar, don't cry. I'll protect you from now on, okay?
Zheng Hengsheng: You have disturbed my heartstrings, aren't you going to keep playing?
When you meet someone, say only a few words, but don't leave your whole heart behind.
