An Older Woman-Younger Man Romance? So What?

Lin Ming was an orphan, adopted by Xu Yuanshan's family when he was ten. Xu Qingya, Xu Yuanshan's daughter, was three years older than Lin Ming. She was gentle by nature, especially toward him.

“Call me big sister,” Xu Qingya teased, draping herself around Lin Ming's neck.

“Big... big sister.”

“Good boy.”

“Now call me your wife.” Xu Qingya breathed into Lin Ming's ear.

Lin Ming jolted awake, his head full of questions. “Aren't you my big sister? Why do you want me to call you my wife?” He truly couldn't understand.

“Come on, be good. You'll understand once you say it.”

(The male and female leads are not related by blood. They're more like childhood sweethearts.)
