Yang Hang: 6th prince, later the emperor. I actually ship them and thought he is the male MC. He is gentle and intelligent. Although he said in the later chapters that he's ruthless. I like their moments together.
Lu Ying: General, adopted brother of BFL. She actually joke around him when they were kids that he will be her husband. She like him first but when he got married (arranged and political) she killed the feeling and stay as just siblings. I love there moments, it's warms your heart.
Fang Hai: Doctor, one of the people she save, not really obvious that he likes BFL but there are hints (or depends on how you will interpret it). It is actually given away in the later chapters.
Bai Pingzi/Lin Pingzi: one of the people she save, not really obvious that he likes BFL but there are hints (or depends on how you will interpret it)
Hai Fushi/Xiao Mi/Gan Sui: male MC. I actually thought that he is the third party. The way he is introduced just made you feel that he is not male MC (since there is Yang Hang). I like him as Hai Fushi, his actions is really cute. Although I would say that I like all of his persona.
