Du Yalin came back from the commissary, and when she went up the stairs, she met Lu Sheng and Li Huai who came down from the third floor.

Li Huai pulled Lu Sheng and yelled because Lu Sheng said that his handwriting was ugly just now, and neither of them noticed Du Yalin who was going up the stairs.

When Du Yalin passed by them, one step higher than them, she turned her head and greeted them, "Lu Sheng, Li Huai, why did you go up to the third floor?" ”

Du Yalin feigned calm. Did you come to her? Du Yalin was faintly looking forward to it in her heart.

But her expectations were doomed to be disappointed.

Lu Sheng and Li Huai turned around and saw Du Yalin standing one step above them.

"Let's go up and find someone...... Are you going to buy breakfast? Li Huai replied, and when he saw Du Yalin holding a loaf of bread in his hand, he asked more.

Lu Sheng stood there silent.

"Yes, but I ate one, I bought too much bread, Lu Sheng, do you want to eat it?" Du Yalin handed the bread to Lu Sheng with her bandaged hand, and the bandage showed a corner under her sleeve.

"I've already eaten it, thank you." Lu Sheng walked directly down the stairs and walked towards the classroom.

Li Huai said "goodbye" and walked back to the classroom, thinking to himself: If you break up and meet again, everyone else will be embarrassed for them.

Du Yalin still maintained that action, smiling self-deprecatingly. A white bandage was wrapped around her left wrist, and I wonder if the wound inside had scabbed over? Perhaps it will leave traces, indelible marks.

Once upon a time, Du Yalin and Lu Sheng also stood on the stairs, and Du Yalin stood on the stairs one level higher than Lu Sheng, looking at each other gently.

As soon as Du Yalin entered the classroom, everyone was gossiping and didn't know what to discuss. As soon as she sat on the chair, Su Li, who was at the same table, told her about Lu Sheng and Li Huai looking for Yi Nan just now.

It turned out that Lu Sheng and Li Huai were here to find Li Yinan, and Du Yalin secretly bit her lip.

"It's none of my business for them to come to Li Yinan." Du Yalin pretended to be indifferent and said duplicitously.

"Arlinn, I admire how quickly you came out of love...... No, it was you who broke up with Lu Sheng, how could you be sad? ”

Du Yalin maintained a proper smile, she disguised it well, only she knew how stiff she smiled and how tired her heart was.

Du Yalin has always been hiding from others, and she secretly likes Lu Sheng.

She didn't dare to go to see Li Yinan, she was afraid of letting others know that she cared about Lu Sheng coming to Yinan. She pretended to be listening attentively, and her thoughts had already flown into the distance.

Before self-study that night, Yi Nan took a math notebook to Lu Sheng.

Lu Sheng looked at the three words "Li Yinan" written on the cover of the notebook, the font was round and cute, neat and small. Turning the first page of the math notebook, although the content is dense, it gives people a comfortable feeling at first glance.

Lu Sheng kept a post-it note at home, and the handwriting on the post-it note was Li Yinan's.

Yi Nan takes notes very seriously, in addition to memorizing knowledge points, there is also an example problem applied to this knowledge point after each knowledge point.

Lu Sheng copied the notes that he had missed before in the evening of the first and second periods of self-study, mastered the knowledge points, and understood some example questions. But there are a few questions that Lu Sheng can't understand, and even if he reads the reference answers copied by Yi Nan, he doesn't understand why he did it.

Li Huai saw that Lu Sheng had been staring at the same problem for a long time, and had been writing mathematical formulas in the sketchbook that he couldn't understand, so he quipped: "Ah Sheng, this kind of big problem is not something we can do, even if we are given the answer, we can't understand it." If you don't understand, forget it, you're still wasting brain cells there! ”

"You're only good for elementary school math." Lu Sheng glanced at Li Huai with contempt.

"If I don't take you to slander people like this, will I still be able to use the Pythagorean theorem and trigonometric functions?" Li Huai said a little humbly.

When Lu Sheng was about to return the notebook to Yi Nan for self-study, he asked a few questions that he didn't know by the way.

After the evening self-study, Lu Sheng and Yi Nan agreed that they would stand by the staircase on the first floor and wait for her.

Yi Nan walked down the stairs with the crowd, she couldn't wait to see Lu Sheng, and she complained a little about the slow flow of people.

Lu Sheng stood by the dimly lit staircase, his angular features obscured by the shadows, his right hand in his trouser pocket, and his left hand holding Yi Nan's math notebook.

Yi Nan recognized Lu Sheng at a glance, because Lu Sheng's figure Yi Nan had peeped countless times.

Yi Nan finally squeezed out of the crowd of people who followed him, and mustered up the courage to walk towards Lu Sheng, Yi Nan clearly felt that the walking posture was not as natural as before, and it was a little timid.

"Have you copied the notes? Otherwise, I'll borrow you again, and I'm not in a hurry to use it. Before Yi Nan walked in front of Lu Sheng, he asked Lu Sheng in a quick voice. Yi Nan was a little nervous.

"I'm done, thank you." Lu Sheng stepped forward and handed the notebook to Yi Nan.

"There are a few questions I don't understand, can I ask you?"

"Absolutely!" Yi Nan burst into a big smile, and suddenly thought that it would be embarrassing if the topic didn't know it himself, so he quickly added modestly: "If I understand." ”

"Are you in a hurry to get home now?"

Yi Nan shook his head in denial.

"Then let's find a bright place."

Yi Nan and Lu Sheng came to the bubble tea shop at the entrance of the school.

"What do you like to drink?" Lu Sheng turned his head and asked Yi Nan, who ordered himself a mango milkshake.

"Me too." Yi Nan wanted to taste the same mango milkshake as Lu Sheng.

Lu Sheng said to the waiter again: "Don't put yogurt in her cup, put fresh milk and heat it." "Yogurt shakes should not be heated.

At this time, the weather is cold in spring, and it is warm and cold.

Lu Sheng took out his math notebook and flipped out the few questions that he couldn't know.

Yi Nan looked at Lu Sheng's handwriting and was surprised. Lu Sheng's characters are just like his people, and they are good-looking. The lines of words are flowing and vigorous.

With a pounding heart, Yi Nan forced himself to calmly talk to Lu Sheng, and Yi Nan encountered many accidents with Lu Sheng tonight.

Lu Sheng not only writes beautifully, but he also has a flexible mind. As long as Yi Nan mentions these questions a little, Lu Sheng will immediately figure them out, and he will draw inferences from one another and solve the other two questions that he can't know.

Yi Nan drank a hot mango milkshake while giving Lu Sheng a lecture. The rich mango aroma lingers in the mouth, and the stomach is so warm.

In the last question, Yi Nan didn't understand the answer either, and said: "I won't know this, I'll ask someone else tomorrow, and I'll tell you." ”

Because Lu Sheng understood it at one point, it didn't take long for Yi Nan to explain the topic to Lu Sheng.

When he was about to leave, Lu Sheng offered to send Yi Nan home, but Yi Nan refused.

"Then I won't look for you next time I don't understand a question." Lu Sheng's tone sounded a little displeased.

Yi Nan said curtly: "Okay, I'm sorry for you." ”

Lu Sheng asked for the address of Yi Nan's house, and after Yi Nan answered, Lu Sheng took Yi Nan to take a different route from Yi Nan to go home in the past.

Lu Sheng and Yi Nan walked one after the other, Lu Sheng walked in front and Yi Nan walked behind.

Because terrestrial people grow tall and have long legs, they will walk with a large pace, at least twice as large as Nan.

Lu Sheng also realized it later, he saw that there was no Yi Nan beside him, so he looked back and saw Yi Nan trotting. In order not to be thrown off by Lu Sheng, Yi Nan trotted desperately, panting slightly.

Lu Sheng stopped, waited for Yi Nan, the corners of his mouth rose, and muttered, "Little short legs." ”

Yi Nan saw that Lu Sheng had stopped and was waiting for her in front, so he quickened his pace. As the distance got closer and closer to the land life, Yi Nan's heart collided like a deer.

Yi Nan and Lu Sheng walked side by side, and Lu Sheng deliberately made his steps a little smaller. Yi Nan's gaze didn't dare to look directly at Lu Sheng, so he could only secretly look at it with his afterglow.

Yi Nan's height had just reached Lu Sheng's shoulders.

The two were speechless all the way, and Yi Nan's mind had been searching for topics to chat about to alleviate the awkward atmosphere, but the words couldn't be said when they came to their mouths.

Yi Nan and Lu Sheng walked to an alley. In the dimly lit alleys, there were a few street lamps that might have malfunctioned, flickering and flickering, and the faint light sometimes shone on the pavement and sometimes disappeared.

Lu Sheng provoked the conversation first: "Do you remember this alley?" ”

"Huh?" Yi Nan looked dazed, not understanding what Lu Sheng said, "Actually, I rarely walk home from this alley, although walking this alley can shorten the time to go home, but because it's too dark, I don't like dark places very much." "I've walked down this alley once or twice. Lu Sheng probably thought that he often walked this alley home, so Yi Nan explained.

"Hmm." Lu Sheng's eyes paused somewhere in the alley for a few seconds, and then quietly moved his gaze to Yi Nan's face, and some memories came back to his mind.

"I took you down this alley, why didn't you stop me in the first place?"

"I don't dare to go alone...... But because you're here, I'm not afraid. Yi Nan said honestly.

Lu Sheng suddenly had a feeling of being trusted, and this feeling was pleasant.

The two quickly walked out of the dim and quiet alley, crossed the lively road, and arrived at the neighborhood where Yinan lived.

"Thank you for sending me back, Lu Sheng." Yi Nan thanked him shyly.

"No, I just want to thank you for lending me a notebook and giving me a lecture."

Speaking of the topic, Yi Nan remembered the unsolved question, and she decided to ask it clearly tomorrow, and then give Lu Sheng a lecture.

Lu Sheng was able to study seriously, and Yi Nan was very happy. Lu Sheng came to ask her to borrow notes and ask her questions, and she was pleasantly surprised.

"Then I'll go first, you can go back quickly."

"Okay."

Yi Nan walked to the entrance of a building, looked back, and found that Lu Sheng was still standing there looking at her, the bright street lamp plated Lu Sheng's body with a layer of golden yellow, as if it was shining on Lu Sheng's body, Yi Nan always felt that Lu Sheng was a person who would shine.

Yi Nan raised his hand and waved to Lu Sheng, blooming with a big smile and saying, "Lu Sheng, bye-bye!" She whispered in her heart, "I like you!" I ran in shyly in an instant, and I felt like my heart was about to pop out.

Lu Sheng watched Yi Nan's back disappear at the entrance, and he also planned to leave.

Suddenly, Yi Nan's voice rang out again, shouting, "Lu Sheng, wait." Yi Nan ran out of the entrance and ran all the way to Lu Sheng's side.

Lu Sheng just wanted to ask what was wrong, and there was an extra warm baby in his hand, which was given to him by Yi Nansai.

"It's still cold, keep warm." Yi Nan said breathlessly, in fact, she ran up to the third floor just now, and ran down from the third floor.

Lu Sheng looked at the warm baby in his hand, and his heart was moved and warm, just like the first time she met him, it warmed him.
