Su Jiu knew what her father wanted to tell her. She was just obediently cooperating with his performance.
When Su Shengjing looked at her serious and humble expression, he choked. He suddenly did not know where to start. At the same time, he felt that he was a man, and it seemed inappropriate to say those things to a girl. Hence, he secretly pulled An Yuan, who was beside him, and gestured for her to speak.
An Yuan did not want to say it at first. She had always believed in Su Jiu's character and knew that Su Jiu was aware of how to protect herself. However, feeling responsible for both her and Su Shengjing, she still gently said, "Little Jiu, from today onward, you'll officially become an adult. You'll begin to come into contact with the world that belongs to adults. That…"
She was a little embarrassed. "You've taken biology classes before. You should know a little about the matters between men and women, right?"
Su Jiu nodded. "I understand."
