Cao An raised the corners of his lips. He liked seeing her innocent look.

Xia Youyou didn't notice the affection between the two, and the monitor also blocked them tightly.

She gestured for Xiao Hai to sit down on the podium, and then began to talk about some computer knowledge so that they could learn about computers more quickly.

Cao An and Xiao Hai were not worried because, after all, they had used their tablets before and should be familiar with computers.

But that was different. Like everyone else, she knew nothing about computers.

Time passed little by little, and Xia Youyou picked up the kettle and took a sip from time to time. She only stopped when people came to the door one after another.

Cao An was afraid that it would have a bad influence on her, so the three of them stood up and asked Xia Youyou to turn off her phone.

They also have to go back to class.

Xia Youyou checked all the window lines before locking the door and leaving the Computer Institute with them.

Cao An looked at the little girl holding his arm and said, "I'll take you back first. You should have a good rest."

"No need to send me off. You guys are about to start class, I can go back by myself." She had a lot of ideas in her mind that needed to be sorted out, and she also needed to edit the teaching materials.

Cao An ignored her refusal, sent Na Ru downstairs to the classroom, watched her enter the classroom, and then pulled Xia Youyou out of the school.

Looking at the thoughtful little girl, her originally chubby face showed signs of gradually becoming thinner in just the past few days.

I was worried but didn't say it out loud, so I could only come back in the evening and make her some seafood to nourish her.

When they arrived at the restaurant, Xia Youyou pushed him back and said, "Hurry up and go to class, don't be late." Then she walked straight into the restaurant without looking back.

Cao An shook his head helplessly and returned to school.

Xia Youyou said hello to her mother and went upstairs. As she walked, she took out some books and began to look for information.

The previous textbook only taught people how to operate and apply it, but the other textbook needs to be disassembled and innovated.

She sat down at the desk and immediately started writing and drawing.

After a busy afternoon, she looked at the table full of papers, raised her head and moved her stiff neck, making a "click, click" sound.

The intercom in the bag also rang at this time, it was Liu Hui's voice.

"Youyou, come down here. I have a phone call."

Xia Youyou felt something in her heart and had trouble breathing.

At this time, it can only be that man.

She guessed that he had just arrived and found a place to call her back to report that he was safe.

Thinking of this, he hurried downstairs without even saying a word and trotted all the way to the public phone at the entrance of the alley.

Liu Hui didn't wait for her response. She was chatting with her aunt who was answering the phone. She was about to pick up the intercom and call again when she saw her jogging towards her from a distance.

I couldn't help but scold her, "Don't run, Si Ling said she would call me soon."

Qi Siling was currently in a public telephone booth next to the train station. If there weren't several people waiting in line behind him to make calls, he would have wanted to occupy the booth and wait for his little girl to answer the call.

There was no choice. The person behind me was urging me to call, so I had to hang up and wait in line again.

Xia Youyou was a little out of breath, so she ran forward and took Liu Hui's arm to calm down.

Liu Hui brushed her messy hair away distressedly, "Si Ling said there were several people waiting in line over there to make a call, so I had to hang up first."

Xia Youyou understood and nodded without saying anything.

She missed him.

After waiting for about five minutes, the long-awaited phone finally rang.

Liu Hui smiled at the woman answering the phone inside, asked Xia Youyou to answer it, and went into the pavilion to chat and laugh with someone.

Xia Youyou's fingertips trembled slightly, but she finally picked up the microphone.

"Hello."

As soon as the voice came out, it was choked with sobs.

Qi Siling on the other end felt bitter in his heart and was speechless for a moment.

The two of them held the microphone in silence for a moment.

They both know what the other person is missing and feel the same way.

Finally, it was Qi Siling who spoke, "Youyou."

"Yeah." Xia Youyou bit her lips tightly to prevent the tears from flowing out of her eyes.

"I just got off the train. Have you eaten well these past two days? Did you kick off the quilt while sleeping? Did I bully you?"

The man on the other end of the phone began to chatter, expressing his concerns.

If I didn't know that the operator was monitoring me, I would have said 'I miss you so much'!

Xia Youyou nodded when he asked a question.

Later it was discovered that the two were only talking on the phone, not face to face, and he could not see his own response.

All I could say was, "I'm fine, don't worry."

Qi Siling expressed her unconcealable longing, while Xia Youyou listened quietly.

In the end, it was the people in the queue behind them who urged them to continue, and they hung up the phone reluctantly.

After paying the five-dollar phone bill, Qi Siling picked up a shoulder bag at his feet and walked out of the phone booth calmly under the astonished gaze of everyone.

Xia Youyou put down the phone in disappointment and was led back to the restaurant by Liu Hui.

She didn't want to be pretentious at all.

But she couldn't stop missing him, like being entangled by vines, making her feel suffocated.

But seeing Liu Hui's worried eyes, she could only hold on and cheer up to go to the kitchen with her to cook.

As for when she is alone, only she knows how dark the night is and how difficult it is to fall asleep.

So she kept herself busy, just like when she was in the Security Department, when she was busy she had no time to miss someone.

Cao An watched her gradually lose weight, and his mouth blistered with anxiety. He tried all sorts of delicious food for Xia Youyou, and she ate it all, but it was no use.

Sighing in the heart, heart disease needs to be treated with heart medicine.

A few days later, Xia Youyou was debugging software in the computer room when she heard the indignant voices of some students coming from far away in the corridor outside the classroom.
