After a long silence, Cao Yu spoke: "Have you rested?" ”

Yuan Nan saw that his face finally eased for a while, so he breathed a sigh of relief and hurriedly said, "Okay, okay, can you tell me about these questions?"

Cao Yu's heart was suppressing his anger, how could he extinguish the fire so quickly, seeing that she picked up the book, with a pious attitude, she couldn't refuse if she wanted to, so she snatched her book with one hand, sat down beside her, and pulled her to sit down, the strength was really a bit big.

"Sit down and listen!"

Yuan Nan was really frightened, her buttocks hurt, she wanted to quickly take a big breath, and seeing that Cao Yu's face was a little darker, she changed the big mouth to a small mouth, and sat quietly on the side without saying a word, listening to his lecture.

"Do you know how you did it wrong?" Cao Yu snorted coldly, "The idea of solving the problem is right, and the answer is wrong!" ”

Yuan Nan was speechless to herself, her father often said that she was sloppy and not careful, not to mention the questions, sometimes she would do the questions, but the answers were often miscalculated by her.

"Which, Cao Yu, you must pay attention next time, you must not make a mistake in such a trivial matter, okay?" As he spoke, he raised his hand above his head, looking like a salute, but said, "I promise!"

Cao Yu pulled her hand down and glanced at her, "Don't always promise in front of me!" ”

"What do you mean always? I remember that I promised in front of you once, where is always guaranteed in front of you, and no boy can let me promise in front of him, you think I am so casual! Yuan Nan said deliberately.

Cao Yu really endured and endured, and finally couldn't bear it anymore, and his anger was aroused by Yuan Nan to the breaking point for a while, he stood up with a black face, and walked towards the door without looking back.

"Cao Yu, don't, what's wrong with me!" As he spoke, he hurriedly stepped forward and grabbed Cao Yu's wrist, and said softly: "Little Cao Cao, I won't speak, okay, don't be angry!" I must not talk nonsense this time, listen to the questions carefully, you see, there are still three questions that have not been taught? ”

Cao Yu's black face finally became ruddy under Yuan Nan's coquettishness. Continue to sit in Fang Cai's seat and get to work.

In this way, after the explanation of a question, although he began to continue to talk about the topic, there was still a layer of refrigerator on his face, "Will this question be done now?" ”

"Hmm......" Yuan Nan nodded hurriedly, indicating that he would.

"Then you do this question first, and I'll come and see it later." With that, he walked out of the room.

When he came to the living room, he saw Li Rong and Grandma Li sitting on the side waiting for him.

Grandma Li said: "Xiao Yu'er, don't be so harsh, you will scare Xiao Nan'er like this." ”

Grandma Li continued to lament: "In the future, speak softly to girls, who else will be your friend like you." Who wants to get closer to you. ”

Cao Yu's face was full of frost: "If you don't want to, you don't want to." ”

Grandma Li scolded with a dark face: "Why don't you listen to grandma!" ”

Li Rong said: "Mom, why do you bother, you should be more strict in your speech, otherwise your thoughts will always love to run the door." Then he said to Cao Yu: "Xiao Yu, don't be angry, your grandmother is such a person, she likes girls more than boys, you don't know, when your mother and I were in college, your grandmother didn't let me hold hands with boys."

Cao Yu's face softened, "Grandma, Mom, you talk first, I'll take a look at the questions she did." ”

"Go ahead!"

Cao Yu turned his head and walked into the house, stopped by what he was seeing.

Someone put a birthday cake in front of them with a very delicate packaging!

The bottom layer is a circle of lilac lace, like beautiful ripples, and the number 12.5 is arranged on the upper layer, and the words "Happy Birthday" next to it are flashing with a happy luster.

"Cao Yu, happy birthday, I originally came here today to give you a birthday gift, but I don't know what kind of birthday gift you like, so I bought you a birthday cake, oh, although this cake is not made by me, but I also went to several stores to customize it for you." Yuan Nan saw that Cao Yu was calm and did not have a shocked expression, so he spoke: "I didn't mean to see your birthday, I only learned about it by accident, so I wrote it down!" Hey, number 12.5. ”

Yuan Nan said very energetically, Cao Yu's heart trembled slightly when he heard it, he hadn't had a birthday for many years, because his mother often forgot it.

"Thank you! I'll accept the gift! ”

"Uh-huh~ But I like your birthday very much, and I'll accompany you every year on your birthday in the future, okay?" Yuan Nan looked at Cao Yu with a smile, so she wouldn't tell him what the birthday book meant, "Okay, it's decided so happily." ”

Cao Yu wanted to refuse, but before he could say anything, she started talking to herself so quickly. He accepted the birthday gift and put it on the table, then turned around and picked up Yuan Nan's homework book, glanced at the question he had just ordered to do, with an expressionless expression, and then said lightly: "This question is good, and when I see this type of question in the future, I will do it in this way." Cao Yu hesitated for a moment and sat down in his seat, "Now let's start the next question!" ”
