Sitting in the office, Gu Nan looked at his mobile phone for the Nth time, with a frown on his face, as if he had encountered some century-long problem.

Nanfeng looked at him with his eyes and his nose, then handed him the document and reminded him.

"Boss, maybe Miss Nuan Nuan is busy with something right now and doesn't have time to send you a message."

That’s right, Gu Nan is waiting for information from his sister at this moment.

In the past, I would send him a message every time at this time to remind him to eat well, but today, I feel like even the meal doesn’t enjoy the appetite.

Gu Nan's strong professionalism made him hold back from twitching his lips. You looked so absent-minded that people who didn't know you would think you had a girlfriend. Maybe even if you did have a girlfriend, it wouldn't be so exaggerated. The Gu family really doted on Miss Nuannuan.

I don’t know if Miss Nuannuan will grow up and get married. I guess her husband will be so outrageous that he will pick up a 70-meter-long sword and chop people.

Gu Nan pursed his lips——"Did something happen to Nuannuan?"

Nan Feng gently reminded her: "You can actually call and ask."

Gu Nan thought for a second and nodded - "You are right."

But it seemed a bit strange to call and ask just because his sister didn't send him a message. It would be bad if it left an unstable impression on Nuannuan.

In fact...he was just overthinking it.

The cell phone beeped twice and then the call was connected.

"Hey? Big brother?"

Gu Nan hummed, but he was not very good at speaking, so he just hummed and said nothing else. Nan Feng was anxious, so he said, "Why don't you say something?"

Gu Nan coughed——"What are you doing?"

A warm and soft baby voice came through the phone - "Mom and I are learning to cook in the kitchen, big brother, are you eating well?"

"have eaten."

"Oh, big brother, you have to come back early today. Nuannuan and mom are waiting for you at home. I am washing fruits now and didn't send you a message. You have to have a good rest and don't be too tired..."

Nuannuan talked a lot, and Gu Nan hummed from time to time, listening very patiently. After this phone call, his frown finally relaxed.

Nanfeng heaved a sigh of relief, and only Miss Nuannuan could make the master feel better.

His grandfather is paralyzed and most of the time he has a cold expression on his face, like a robot, although he looks very handsome and cool.

But sometimes when he was in a bad mood or felt depressed, although the expression on his face did not change, his aura became stronger and more oppressive, causing everyone around him to tremble with fear. The bad thing was that his face was always expressionless and no one could guess what was wrong with him.

Only Nanfeng, who had been by his side for many years, could occasionally guess his mood.

As soon as he hung up the phone, Gu Nan immediately turned on the workaholic mode, really like a robot, sitting upright in the office chair with two computers in front of him, hosting two meetings abroad at the same time, and the meetings were held in different languages.

At the same time, he carefully read the document he had just been given, pointed out several problems in it, and asked Nanfeng to take it away for rectification.

“Okay boss!”

Nanfeng left with the documents and a standard smile on his face, clenching his fist as he walked to the door.

My heart instantly turned into a crazy fanboy screaming.

Ahhhh!! As expected of his boss, he is so cool at work!

In just a second or two, he turned into that strict and perfect assistant again.

Gu Nan was always thinking about what Nuan Nuan said today about going home early. So he worked hard for several hours, and his sitting position basically did not change. Finally, he finished processing all the meeting documents and stood up, picked up the windbreaker, threw it behind him, and put it on himself in a particularly cool way.

"Grandpa, there is a party..."

Gu Nan didn't even think about it - "Reject it."

Then, while Nanfeng was hesitant to speak, he went directly to the underground parking lot, got in the car and closed the door in one go.

"Grandpa, but that party..."

"No."

Nan Feng——“…”Please let me finish my words first.

But under his cold and emotionless gaze, Nanfeng still didn't dare to say anything. Never mind, it's not me who will be scolded anyway.

Nanfeng drove to Gu's house.

Shen Yujin, who had prepared a dinner for someone's birthday with someone's consent the day before but was stood up - "..." He looked at the time with a gradually cracked expression.

At this time, Gu Nan had already returned home, but the quietness of the house made him a little confused.

He pushed the door open with a bang and colorful firework streamers fell from the sky onto his head, making his black hair instantly shiny.

Staring at the ribbon hanging from his head in front of him, Gu Nan's expression was rarely dull.

"Happy birthday, Boss!"

"Happy birthday, big brother!"

Suddenly, he heard a noisy sound. He turned around and saw the whole family except his second brother gathered around him.

His dear sister and mother were holding firework sticks in their hands and smiling happily.

Gu Nan——“…” I basically haven’t celebrated my birthday at home since I grew up. One reason is that I was really busy, and the other is that I thought it was childish.

Unexpectedly, his family gave him a surprise today.

She took off the ribbon on her head and asked calmly, "Why did you think of celebrating my birthday?"

Nuan Nuan looked at him eagerly - "It's Nuan Nuan who wants to celebrate big brother's birthday."

As she said this, she opened her little arms and fell into her father's arms.

Gu Nan caught the little girl easily.

"Happy birthday, big brother! We have prepared a gift for you."

Gu Nan nodded, walked in holding Nuannuan, and then saw the birthday cake on the table. Perhaps because they knew that he didn’t like such sweet desserts, the surface of the cake was inlaid with various fruits.

"Big brother, this is made for you by my mom and I."

Gu Nan looked at the cake and then at the little boy in his arms, and the corners of his mouth curved slightly.

"Yeah, thank you."

"You're welcome, come and eat. It's a pity that my second brother won't be back today."

Just as he finished speaking, a gentle voice with laughter came from the door.

"Who said I wouldn't come back?"

The little girl in Gu Nan's arms widened her eyes in surprise when she heard the familiar voice, and twisted her neck to look outside. At the same time, Gu Nan also turned his head to look over.

There was a tall and handsome young man standing at the door. His short black hair was blown by the wind. Under the light, his face was similar to Gu Nan's but with a gentle smile.

“Second brother!”

Nuannuan shouted with joy.

Gu Nan put her down, and Nuannuan ran over quickly with her short legs, and immediately hugged the person at the door.

"Second brother."

Perhaps because he had just rushed back from outside, Gu Bei felt a little cold. But Nuan Nuan didn't care about that. She hugged his neck tightly with her little arms and buried her whole little face in his neck like a kitten.

The little girl's eyes turned red after not seeing her second brother for so long, she looked like a pitiful little rabbit.

Gu Bei held the little one in his arms, he missed his sister too.

The research, which was supposed to take some time to complete, was completed by him working overtime and staying up late. Of course, there might be a bit of luck involved, but it did not prevent the result from being perfect.

"Teacher...Professor!"

During this warm moment, two guards who were almost crushed by the luggage called out to the professor with difficulty.

Gu Bei rubbed Nuannuan's little head and looked with a smile at the two young and strong guards who were originally protecting him.

"Oh sorry, please put your stuff in there."

The two of them quickly carried the large and small bags inside and put them down, then performed a standard military salute, "Please take them."

Looking at the large and small bags of things on the ground, the Gu family - "..." Mother Gu's eyelids twitched - "Are these all from my little waiter?"

One of the guys laughed. “Yes, they are all from Professor Gu, but… there are more.”

After saying that, the two of them ran away again, followed by Comrade Mu Qing, who was grunting as he carried the luggage.

"Professor, you have a truck with your stuff!"

Everyone——"…" What on earth did you buy?

Gu Bei smiled a little embarrassedly - "These are some gifts I bought for everyone in City A, and some of my experimental equipment."

It took several young people several trips to move all the things Gu Bei brought back. Looking at the things that were almost piled up like a small mountain, Gu Bei was indeed a talented person!

It took everyone a long time to sort out all the things together, and the gifts he bought for Nuannuan took up four large suitcases.

Nuan Nuan's eyes were stunned.

Father Gu patted the shoulders of several young people and said in a heavy tone: "Thank you for your hard work."

"It's not hard."
