"It's okay, you're right, it's a little early." Xu Li followed Li Antong's words and said, she originally thought that Li Antong, as a high school student, should make it a lot easier for him to get out of school at half past five, so she mentioned cram school, but since Li Antong herself didn't feel troublesome, she was a stranger and didn't say much.

"I just saw Yiyi standing alone at the door of the store, a little uneasy, now that you are here, I still have something to do, so I will go first."

Feeling the young man's discomfort, Xu Li didn't entangle, anyway, her curiosity had been satisfied, and it would be boring to interfere too much with other people's privacy.

"Thank you, Mr. Xu." Li Antong was about to get up when he was stopped by Xu Li.

"No need to send it, the cake I ordered hasn't been served yet, remember to order it for Yiyi, don't steal it."

Saying that, Xu Li waved his hand and left, leaving Li Antong with a stunned face.

"Xiao Yi, this teacher is really ......" Li Antong was stunned for a moment, he still thought that Teacher Xu was a serious and rigid person.

It was the first time he had seen such a young teacher, and he didn't look much older than himself.

But it's a good thing that Xiaoyi has such a teacher.

Looking at Li Ziyi, who was still in a daze, Li Antong shook his head.

"Let's go, go home." Hugged Li Ziyi from his body, Li Antong said.

"Brother, the cake ......" Li Ziyi was obviously still thinking about the cake that didn't come up.

"Waiter, don't serve the cake on this table...... Pack. ”

When he heard Li Antong say that he didn't need to go on, Li Ziyi's little face collapsed, but he smiled again after hearing the packing.

"Cake, cake ......"

"Does Xiao Yi like cakes very much?" On the way home, seeing Li Ziyi chattering, Li Antong asked.

"Yes, I like it."

Looking at the glint in the little girl's eyes, Li Antong said, "I like to buy it for you next time."

……

Evening.

"I'm back, it's so hot today." Closing the door, Shen Aya took off the schoolbag on her body and said while taking off her shoes.

"I've told you about it, it's been around the hottest lately...... Come back soon after school, if you are fat, you have to lose any fat, and it is not good-looking......" A lazy voice came from the living room, although it was soft, but it was very mocking in Shen Aya's ears.

"Hmph......" Shen Aya stomped her feet and stopped making a sound, her past experience told her that she would suffer if this kind of thing continued.

But you can't just let him go, since you can't say it, then it's better to retaliate with actions.

Walking into the living room, one big and one small were lying on the coffee table, staring at a homework book.

"Here."

"Well...... And this question, right? Let me see ......"

Cut.

Seeing that Li Antong was teaching his little sister to do the question, Shen Aya's fist gradually loosened, and slapped him on the shoulder with a palm.

"I'm going to take a shower, remember to cook."

Now it's the right thing to take a good shower and relax, she is sweating after running, and her body is sticky and uncomfortable.

"Got it, let's go, it stinks." Li Antong waved his hand with a disgusted expression.

"You!" Shen Aya gritted her teeth and looked at the person in front of her, who still looked at the homework book in his hand with an uncaring look.

Is this person really his brother, why is he so annoying, forget it, don't worry about him.

Leaving a cold snort, Shen Aya took a change of clothes and walked into the bathroom.

The bathroom was hazy with steam.

"Ah, I was cured, and sure enough, it was the best to take a hot bath after running, but it was a little stuffy." Shen Aya lazily lay on the edge of the bathtub, took off the towel with her hair coiled, and let her hair float freely on the water.

"Now it would be nice to have a glass of juice." Thinking of this, Shen Aya raised her head and looked in the direction of the living room.

"Forget it, I don't want to see that annoying guy."

When I think of him, I am very angry, really, where is I fat.

……

Outside the bathroom, Li Antong stared at the exercise book in his hand, a drop of cold sweat oozing from his forehead.

The topic is - Xiao Ming and Xiao Hong went to Xinhua Bookstore to buy books, both of them didn't have enough money, Xiao Ming brought six yuan less, Xiao Hong brought four yuan less, the two of them together are just enough to buy a book, how much is this book?

Li Ziyi stared at Li Antong with wide eyes and a puzzled expression.

"Why ten dollars?"

"Well, let me think about how to explain it." Li Antong knew the answer to this question at first glance, as if it was instinct, and the answer was ten seemed to be common sense.

But what should I say......

Li Antong was still thinking about it here, when he heard Shen Aya's voice behind him and looked back.

Shen Aya was wearing a T-shirt on her upper body and hot pants underneath, her hair was wet and sticky together, and there was a faint heat on her body.

"Washed? How not to blow dry your hair. Feeling the moisture, Li Antong frowned.

"You care about me." Shen Aya replied, and then laughed.

"What about high school students, are you an idiot? Thinking about a second-year topic for so long? ”

“……”

"Yiyi, let my sister teach you, my brother is a fool."

Li Ziyi glanced at Li Antong as if he didn't understand, and then handed the exercise book to Shen Aya.

"Let me see ......" Shen Aya took the workbook, and after reading the questions, she looked at Li Antong with some disdain.

"The answer is ten yuan, Li Antong, you are really stupid when you say that you are stupid, you can't do this kind of second-grade question, are you sleepwalking?"

Spit out all the unhappiness in her heart in one breath, and Shen Aya only felt comfortable physically and mentally.

"Yes, but why ten dollars?" Li Ziyi was puzzled, her brother had already said that it was ten yuan just now, but she still couldn't understand it.

"You see, we set the price of this book at X yuan, in this way, Xiao Ming will bring X minus six yuan, Xiao Hong ......" Shen Aya bent down and wrote down the formulas on the paper.

After hearing Shen Aya's first words, Li Antong covered his face.

This one...... A sucker.

"Xiaoyi, meow one." Looking at Li Ziyi, who was confused, Li Antong said.

"Huh?" Although I didn't understand why, Li Ziyi still meowed obediently.

"Hey, what are you doing, I'm giving Yiyi a lecture." Shen Aya said dissatisfied.

"Xiaoyi, look at it, what is this?" Ignoring the fried Shen Aya, Li Antong pointed to the X on the paper.

"I know this, the teacher taught it a few days ago, it's a multiplication sign, and I also memorized the multiplication formula, one by ......one, one by one," Li Ziyi broke his fingers, and then memorized the formula.

"Well, Xiaoyi is the best." Li Antong touched Li Ziyi's head, and then glanced at Shen Aya.

"What do you mean......" Seeing the smile in Li Antong's eyes, Shen Aya was about to ask clearly, but she was suddenly stunned, and then her pretty face turned red at an unimaginable speed.

Li Ziyi is only in the second grade, how can he understand equations......

Damn, damn it, it's a shame......

"Little sister?" Seeing that her sister's face was flushed and steaming, Li Ziyi wondered.

Just then, the doorbell rang.

"I'll open the door." As if relieved, Shen Aya left the living room as if she had escaped.

“…… Stupid girl. Li Antong shook his head, picked up a coat and followed.

"Xinhua? What are you doing here. Opening the door, Shen Aya said with some surprise.

The girl at the door was dressed in neat yellow clothes, with short ear-length hair, and a pair of big round-framed glasses on her small and delicate goose egg face, which brought a little literary temperament to the girl with the lenses that occupied half of her face.

"Aya you...... How do you dress like this. Wang Xinhua's face was covered with a flush, and she couldn't accept Shen Aya's avant-garde dress, knowing that they were only junior high school students.

"What does it matter?" Shen Aya replied nonchalantly.

After seeing the person clearly, Li Antong casually hung up his coat.

"Xinhua? Come in and sit. ”

Wang Xinhua, the girl in the neighborhood, is the same age as Shen Aya, and the relationship is also very good.

"No, no, Ann... Brother Antong, I, today, dad he ...... This is ......" The girl is very introverted and can't speak clearly when she is nervous.

"Let's sit down first." Shen Aya couldn't help but pull Wang Xinhua in.

"What is this?" Li Antong noticed the bucket next to the girl and asked.

"Today, a relative sent a lot of fish, and I couldn't finish eating it, so I wanted to bring some over, I... I...... I remember that Brother Antong likes to eat fish. Wang Xinhua whispered.

"Cut, why don't you remember that I hate fish the most." Shen Aya pouted.

"Aya ......" Wang Xinhua gently pushed Shen Aya.

"Okay, okay, don't make fun of you, come in and sit."

"Sister Dictionary!" After Li Ziyi saw Wang Xinhua, she ran over and hugged her.

Everyone is an acquaintance, Li Ziyi is naturally no stranger to Xinhua, and even gave her a nickname because Xinhua's name is homophonic to Xinhua Dictionary.

"Call Sister Xinhua." Li Antong glanced at Wang Xinhua apologetically and said to Li Ziyi.

"No... It's okay. Wang Xinhua waved his hand, looking unconcerned.

"What are you doing?" As soon as he saw Li Ziyi, the tension in Wang Xinhua's heart dissipated and asked.

"Do your homework." Li Ziyi replied obediently, pointing to the homework: "This question will not be." ”

"I'll see, well, the answer is ten." Similarly, Wang Xinhua came up with the answer after just one glance.

"Why?" Li Ziyi asked.

At this time, Li Antong and Shen Aya also pricked up their ears, wanting to hear how she explained.

"Look, they were going to buy two books, one for each person, didn't they?"

"Yes!" Li Ziyi nodded vigorously.

"But in the end, I only bought one, and I didn't buy one yet, right? But how much is the difference? ”

"Six plus four, I understand, they can buy another book for ten yuan, and a book is ten yuan!" Li Ziyi snapped her fingers, and then said happily.

"That's smart." Wang Xinhua touched Li Ziyi's little head and praised it.

After listening to Wang Xinhua's explanation, Li Antong and Shen Aya glanced at each other, which ...... Okay?
