The male protagonist (Li Jinyuan): A top boss, cold and paranoid. He hurt the female protagonist in the early stage due to his original family/misunderstanding (for example, thinking that the female protagonist set him up and hurt Bai Yueguang). Only after losing him did he learn to cherish. When chasing his wife, he must be "abusive" - put down his body, endure humiliation, and even sacrifice his interests. The sense of contrast is the key.
The female protagonist (Su Wanqing): She is gentle and tolerant in the early stage, has artistic talents (such as designers, painters), and has inner resilience. She will never leave after being broken. After growing up, she will be independent and sober. She is not love-minded. She remains vigilant in the face of the pursuit of the male protagonist and needs to see actual changes before she will waver.
