Xu Qinghuan is Li Nian's half-sister
The first time Xu Qinghuan saw Li Nian, she hated her to the core because she had taken away her little father's love. But later, Li Nian used love to influence her again and again, which made her develop a different kind of emotion towards Li Nian.
The first time Li Nian met Xu Qinghuan, he fell in love with her stepsister.
In the end, the two finally confirmed their relationship, but their parents found out that although their parents didn't understand, they still respected it.
"The love I long for has no gender distinction. Gender is not a shackle that traps our love. As long as we love each other, we can overcome everything."
"Qing Huan, do you know that I had a different kind of emotion for you the first time I saw you? This emotion goes beyond sisterly love."

Concept: Love is gender-neutral. If you love each other, don't hesitate. Hesitation will only leave regrets.
