Taking advantage of my girl brother's stupidity, trick her into being my wife

At this time, Xiaoyu also had an expectant expression on her face, and she looked at Chen Kai so eagerly that he didn't know whether to laugh or cry. For a moment, she really didn't know what to say.

So he said speechlessly:
"Xiao Yu, why do you think about playing all day long? I took you to the library to study this morning, but now you have completely forgotten everything."

"Don't go out to play tomorrow. Study at home, review well, and read books."

When Xiaoyu heard him say this, he immediately shook his head, then patted his chest and promised:
"No, Lao Chen. I, Qin Xiaoyu, have the best memory. Even the best memory in the world is not as good as mine. What I learned in the library this morning is already memorized in my head. I won't forget it."

"How could I forget everything just because I went out to play all afternoon? Is my memory that bad? It's impossible!"

Xiaoyu immediately patted his chest and made a solemn promise.

Chen Kai was also skeptical and looked at it with some confusion: "Is it really like this? How about a test in class?"

"If you can answer all three of my questions, I'll take you out to play tomorrow."

When Xiaoyu heard him say that, she felt a little guilty for a moment. Chen Kai deliberately teased her: "No, I don't dare."

"How could that be? Why would I be afraid?" Xiaoyu patted his chest and made a solemn promise. Then he continued, "Old Chen, we are ready and can start anytime."

Hearing Xiaoyu's comment, Chen Kai immediately replied, "Okay."

“Then I started asking questions.”

As a result, an embarrassing thing happened. Xiaoyu couldn't answer the first question Chen Kai asked.

I reviewed it this morning and I remembered it clearly. Why can't I remember it now? Xiaoyu touched his head and kept knocking it: "Oh, why can't I remember it? Lao Chen, give me another 30 seconds to think about it."

"I'll give you ten minutes. Take your time to think about it. I'm not in a hurry."

Ten minutes passed, but Xiaoyu still hadn't remembered. "Okay, I won't..."

Chen Kai just took a sip of water, and when he heard Xiaoyu's sincere answer, he choked for a moment. "Xiaoyu, you are really honest."

"I don't know how to do it anyway... But Lao Chen, I will definitely study hard tomorrow, but we should always combine work with rest."

"I can't think about studying every day and not even have time to play. If I study for a long time, won't I become a nerd? I don't want to become a nerd!" Xiaoyu replied immediately.

Chen Kai was also speechless. He thought to himself, it might be possible for others to become nerds, but for you, there is absolutely no possibility!
Chen Kai smiled helplessly: "Okay, okay, I'll take you out to play tomorrow, okay. But you must not fall behind in your studies. Look at your recent studies, they are really getting worse and worse."

"If you fail the next exam, I think you should go back to the dormitory then."

"Let's not live outside anymore, so as not to affect your studies."

Xiaoyu patted his chest quickly and assured: "Don't worry, Lao Chen, I promise I won't fall behind in the next exam."

"Don't ask me to go back to the dormitory. I don't want to go back to the dormitory!" Xiaoyu was a little anxious and promised: "I will definitely improve my grades." (End of this chapter)
