Gu Nan ran a lap and then ran back to pick up Nuannuan. His clothes were almost soaked with sweat.

He has a physique that tends to sweat easily. The loose sportswear stuck to his body, revealing his tight abdominal muscles and a slender and well-proportioned figure without a trace of fat. If some girls saw this, they would probably scream.

Nuannuan followed her brother home with her short legs. She didn't have to run, it was just like taking a walk and she didn't feel tired at all.

After breakfast, she sent her elder brother to work and Nuannuan started to learn the guqin.

Previously, Su Ran came and personally taught Nuan Nuan the various fingerings and key points of piano practice. Now Nuan Nuan can also play a simple song slowly and received praise from the teacher.

"Nuannuan, please play this song to familiarize yourself with it. I will teach you the others later. It's great that you can play one song in just a few days."

Su Ran went back after Nuan Nuan's birthday, and now she is teaching online again. But there is a smart student who can learn very quickly and well even with online video teaching. Su Ran feels very fulfilled to teach Nuan Nuan how to play the piano.

The praised little Nuan Nuan smiled shyly, her dimples were so cute and soft that one really wanted to touch her little head.

"It's because the teacher taught me well."

Nuannuan spoke modestly, and then played the piano piece again. Her slender white fingers were wrapped with false nails, and the movements of plucking the strings went from unfamiliar to proficient. The piano piece also went from being hesitant at the beginning to being smooth in less than an hour.

Nuannuan has a clean and simple mind, and the piano music she plays also has a clean feeling, which makes people feel very comfortable when listening to it.

Su Ran was amazed at Nuan Nuan's learning speed, and was later attracted by her piano playing.

The young boy looked at the little girl sitting on the piano bench practicing piano music over and over again. She was like a white jade ball, and she was very serious and focused in everything she did.

She is really born for music.

After piano lessons were over, little Nuannuan took a nap, then got up and took her cousin to her older brother’s Nanjinbiewan to see the vegetables and strawberries he had grown.

The two of them ran to the field to manually weed the vegetable patch to prevent the weeds from growing and stealing nutrients from the vegetables. Their fair hands became dirty, and when they raised their heads they realized that both of their faces were dirty.

When Gu Bei came and saw the two of them——"..."

“Second brother!”

Nuannuan waved happily at Gu Bei with a dirty little face.

"What are you doing?"

They both said in unison: "Weeding."

One is soft and glutinous while the other is clean and refreshing. Bai Mohua and Nuan Nuan together are like children who have not grown up.

Gu Bei sighed as he looked at the two people's dirty faces. Forget it, as long as they are happy...

It's just... it would be better if he wasn't dragged down as well.

Gu Mingli thought that he had finally escaped the hellish days of his sister asking for tutoring after he went to school. But at night he realized that he was too naive.

The little girl came over via video at the right moment.

The little guy in the video looks so cute, so soft and small. But when the camera is focused on the textbooks on the desk, he is not cute at all.

Gu Mingli, who never had any worries, was a little worried. Are all the homework for first graders so difficult now?

But after worrying about it, I still have to continue to help my sister with her homework.

So that day, all the roommates in the dormitory were horrified to find that after Gu Mingli returned to the dormitory, he did not play games, but... took out a pen and paper.

Tang Le went over to take a look and was horrified - "Brother Gu, if you are possessed by some weird thing, just make a sound!"

Wu Kuang gestured wildly with his hands, then rolled up a piece of paper into a tube and used it as a demon-killing sword.

"Hey! What kind of monster dared to possess my brother Gu? Is he tired of living?"

Lu Xingzhi——“…” He is so tired of having to deal with two idiots every day.

But Lu Xingzhi also felt that Gu Mingli suddenly started to learn... a strange feeling, like the sun rising from the east.

Gu Mingli scratched his hair and was originally quite depressed. But when he was disturbed by his two roommates, he stood up and kicked each of them.

"Get away from me and don't disturb me while I'm solving the problem."

Lu Xingzhi walked over and saw something, then looked at the problem he was solving, which turned out to be a first-grade math problem.

Lu Xingzhi——“…”

"Are you... tutoring Gu An?"

"It's Nuan Nuan."

The little girl's tender face appeared in front of the camera, and she looked at them a little embarrassedly.

"Hello, Brother Lu, Brother Tang, Brother Wu—"

A soft greeting was heard, and Tang Le and Wu Kuang reacted and rushed over.

"Hello, sister. Have you had dinner yet?"

Nuan Nuan answered obediently - "I ate it."

Gu Mingli glanced at them - "Isn't that nonsense? Who hasn't eaten yet at this hour?"

Wu Kuang retorted: "Then we have to have some midnight snack!"

Gu Mingli——"Do you think everyone is a pig like you?"

After joking around for a while, the two of them finally had to face reality, so Gu Mingli sat down and continued to solve the problem for Nuannuan.

After finishing, he sat on the chair with a dejected look on his face.

"The textbooks used by elementary school students nowadays are so abnormal, and I have almost forgotten everything I learned in elementary school!"

He was afraid that one day Nuannuan would come to him to ask questions and he wouldn't be able to answer them.

Lu Xingzhi looked at Gu Mingli thoughtfully.

"Nuan Nuan didn't ask anyone else to help with her homework?"

Gu Mingli replied with a little pride: "If you want Nuannuan, just look for me."

This is such a sweet burden.

Lu Xingzhi raised his lips, and he probably knew what the little girl was going to do. As a good brother, he certainly hoped that Gu Mingli would get better and better, so...

"You'd better pick up your studies. Otherwise, you will be embarrassed in front of Nuannuan if you can't even answer the questions in the first and second grade."

Gu Mingli wiped his face and said, "Okay."

As for Nuan Nuan, she was really worried about her fourth brother's initiative to study. Not only did she often go to him with her textbooks, but she also applauded and praised him after he answered the questions, with her pure eyes full of admiration.

"Fourth brother, you are so amazing. You have solved such a difficult problem."

Although he was very smart and arrogant in front of other people, he was so happy in front of his sister that he was flattered by a little compliment and an admiring look. Then he devoted himself to study more willingly.

Lu Xingzhi didn't know what words to use to describe his complicated feelings. So many people had advised him before, but none of them was as good as a compliment from a kid.

Gu Mingli's slight change caused quite a stir in the class. Several poor students who were good friends with him looked at him as a "traitor", and then were glared back at by the hot-tempered Gu Mingli.

"What are you looking at? Don't mess with me if I'm upset!"

Well... Gu Mingli, who was memorizing words, became more irritable. Even Tang Le didn't dare to disturb him while he was memorizing English words.

Tang Le - "It's been five days. I can't believe that Brother Gu has already been studying for five days!"

Wu Kuang nodded with a serious expression - "I can only say that my sister has had a huge influence on me."

Lu Xingzhi was also reading a book. He laughed. "Isn't this good? You two should hold on tight. Otherwise, if Gu Mingli gets admitted to university and you two drop out or only go to a third-rate university, the distance between you will grow bigger and bigger. Your relationship won't be so good in the future."

Tang Le and Wu Kuang were stunned for a moment, then fell into deep thought.
