In the next long ten minutes, Chaochao finally gave up struggling, sat on the stool, and listened drowsily with listless eyes.

When Zhao Di finished drawing the draft and turned around, she tried her best to focus on his face, nodded solemnly, and then when the old man turned back, her firm almond-shaped eyes instantly lost their light.

As Zhao Di spoke, he drank water. After finally finishing explaining an important detail, he pushed the draft paper in front of the children. "I'm going to the restroom first. Chaochao, take another look at this diagram to reinforce your understanding."

"Oh, right," he suddenly remembered something, paused in his act of getting up, turned to the boy who was casually looking at a competition practice book, and said, "Yu Shen, come with me for a moment."

Pei Yu nodded and put the booklet away.

Seeing that she seemed to be the only one left in the office, Chaochao, who was still half asleep, suddenly jolted awake and asked in a surprised voice, "...Huh?"

Zhao Di asked Pei Yushen outside the office if he had been harassed at school that day. When he heard the boy calmly say, "Yes, but it's been resolved," he paused for a moment, then smiled sincerely. Zhao Di had many other things he wanted to say to his most valued student, but in the end, he only said one sentence: "Everything will be alright."

The man, who had aged considerably in just one year, chuckled and sighed as he waved and walked toward the restroom.

When Pei Yushen returned to his office, he didn't see the little dumpling in the chair at first glance. He frowned and looked at Wang Jie next to him. Just as he was about to speak, he suddenly noticed a dark shadow moving slightly in his peripheral vision.

Pei Yushen paused, the words he was about to say, and looked to the side.

Then,"…………"

With his heart gradually calming down, Pei Yushen calmly called out to the globe that had suddenly sprouted two little tufts:

"Every morning".

The little dog Chaochao, hiding behind the globe, shuddered and slowly peeked out from behind the globe with a big, suspicious look in her eyes: "Brother Yushen, how did you figure that out?"

She hid her head very well!

Because I've never seen a globe with two fluffy ears before.

However, Pei Yushen didn't say it outright. Instead, he made a vague point: "I just saw the Earth being blown around."

Chaochao repeated it once, and after understanding it, her eyes suddenly widened. She turned her head sharply to look at the globe in front of her, her little eyes sparkling with surprise.

She just succeeded?

Could it be because I was too nervous just now and exhaled a lot of air?

Overwhelmed with joy, Chaochao instantly forgot to question Pei Yushen. But before she could try again, she heard footsteps approaching the office door, growing louder as they went on.

The little dumpling's excited face froze instantly, and it quickly hid its head back behind the globe.

"Okay, let's continue... wait, where's Chaochao?"

As Zhao Di stepped into the office, he looked at the empty desk and chairs and asked Pei Yushen, who was sitting calmly to the side, with a puzzled expression.

The little head behind the globe twitched slightly.

"Yu Shen, look—oh, so that's where it was!"

Chaochao, who was practically hypnotizing herself into a ball: "..."

After taking a few steps forward, Teacher Zhao suddenly spotted Chaochao's reflection in the windowpane and immediately walked over happily.

"Is Chaochao studying world maps here? What a studious child. Perfect timing, let me tell you about Europe..."

"Teacher Zhao."

Suddenly, Pei Yushen spoke up.

"It's getting late, and I have a doctor's appointment later, so I have to leave now."

Once reminded, Zhao Di glanced at the wall clock and realized he had unknowingly attended a half-hour science lesson.

"It's been so long..."

He paused, clicked his tongue in regret, then smiled and said,

"Then I won't take up any more of your time, go back now."

As soon as these words were spoken, Zhao Di felt a glint of light in his eyes.

He looked down and saw the little boy who had been sitting there watching the game just a moment ago now standing energetically at his feet, taking a small step forward just as he had come, and solemnly shaking his hand:

"Zhao Laosi, we'll be back!"

Zhao Di smiled kindly: "Okay, when Yu Shen comes back, bring Chaochao with you too. I'll continue to teach you the most basic physics theorems. Now that you've had your math introduction, you can't neglect physics either."

After Zhao Di finished speaking, he saw the child's adorable expression freeze slightly, which made his own smile even brighter.

Pei Yushen had long since realized that his teacher was deliberately teasing Chaochao, and the only one in the entire room who was still unaware of it was the little dumpling who took it seriously.

"I...I think I had something to do that day..."

After pondering for a long time, Chaochao finally managed to utter a sentence.

"Oh? What is it?" Zhao Di asked curiously.

Eat? Sleep? Watch cartoons? Water the plants? Collect stones?

Chaochao went through her daily routine in her mind.

Yes, these are all very important things.

"I need to accompany Daddy to work."

In the end, the little dumpling shook its head and sighed, its tender face full of "helplessness, but there's nothing I can do but spoil it."

The whole teasing of the children ended with Zhao Di, who was amused himself, waving his hand and telling them to be careful on their way home.

Even after Pei Yushen and Chaochao left the office, the student who had been invisible by the office door for half a day, holding a physics test paper, still stared incredulously at Teacher Zhao Di, who had been treating the boy and girl with kindness the whole time.

Is this really his usually stern and unsmiling special instructor?

After leaving the office, Pei Yushen quietly moved to the side. The little girl sighed and climbed into the wheelchair. The boy silently withdrew his hand, which had been protecting the armrest to prevent her from hitting her head. Neither of them spoke a word during this time.

System: ...How many years have you two been working together?

As Chaochao sat in the little car, I touched her head, which had suddenly been permeated with knowledge, and let out a long sigh in an old-fashioned manner for the umpteenth time.

She learned so much today, she must have worked so hard.

Make sure to tell your aunt to prepare a little extra for dinner!

Thinking of this, the melancholy and haggard little dumpling instantly brightened up. She chuckled twice, turned her head and hugged Pei Yushen's arm, rubbing against it.

Pei Yushen looked down and saw a certain cub nuzzle against him twice, then suddenly raise its head and open its bright almond-shaped eyes, "Brother Yushen, do you like Zhao Laosi?"

Pei Yu raised an eyebrow slightly, looking somewhat surprised.
