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.”

However, Su Jiu knew these things only in theory and had never put them into practice.

When she thought of the little villain’s increasingly handsome face, her heart could not help but beat faster. If she were being honest, Su Jiu felt that in the face of such a fatally attractive man, she was already impressive to have endured it until now without putting these things into practice.

This self-control is something to be proud of, right?

Although An Yuan was embarrassed, she tried her best not to show it. Smiling, she said, “Mommy doesn’t object to you exploring the world of adults, but… I have something to remind you of. Girls have to learn to protect themselves. After all, if there’s anyone that will suffer from a relationship, it’s us girls. If you accidentally have a baby, can you handle it?”

When Su Jiu heard this, she could no longer remain calm. Her heart beat faster, and her face turned slightly red. “Mommy… I… I haven’t thought about wanting a baby.”

“Mommy knows. Since you don’t plan to have a baby, you have to pay more attention to protecting yourself.”

Su Shengjing coughed lightly and looked rather embarrassed. However, he still seriously said to Su Jiu, “Little Jiu, your mother is right. You’re the only child we have. You’re still a girl. If you suffer, your mother and I will feel sorry for you. It might be difficult for me to control my urge to beat that brat up.”

Su Jiu forced a smile. “I know. I’ll be careful. You really don’t have to worry.”

“It’s best if you can say that.” He nodded. “But you can’t just say it. You have to remember it.”

“Yes, yes, I will.” Su Jiu nodded vigorously.

Only then did Su Shengjing’s expression ease into something lighter. “Alright, it’s very late. Go to sleep. Don’t stay up late just because it’s your birthday.”

When Su Jiu returned to her room from the living room, she realized that someone was standing at the door of her room.

The faint yellow light in the corridor outlined the handsome and deep outline of the young man. His expression could not be seen clearly, but it was inexplicably fatally attractive, making people want to approach him and investigate.

Su Jiu quickened her pace and pounced on him with a smile. Rong Si naturally reached out and let her throw herself into his arms.

Su Jiu lifted her head from his embrace. “Why aren’t you asleep yet?”

“I’m waiting for you. The birthday girl is still awake. How can I sleep as a guest?”

Su Jiu looked down at him. Perhaps it was because the light was too effective, but his eyes looked exceptionally gentle. Su Jiu’s heart softened. She wrapped her arms around his waist and said, “You’re not a guest.”

“Oh? Then what am I?” Rong Si raised his eyebrows with interest.
