The sky that the red sun sets in the west and looks at in the distance is how many days and nights are touching.

As soon as I got home, I lay down in bed, so tired from a long day at the amusement park that I could fall asleep just by closing my eyes.

But just as I was about to fall asleep, I heard the ringing of my mobile phone. To be honest, I really don't even have the strength to listen to the phone now, but when I saw that it was Professor Wu's phone, I still picked up the phone.

"Hello, Cheng Yin, I'm really embarrassed to call you so late."

Professor Wu's voice came from inside the phone.

"It's nothing, Professor Wu, I haven't slept anyway. But is there something important about your late call? I asked.

"There are indeed some important things, can you and Cui Li come to my office together tomorrow morning? You may need some information about the last AEF Research Center. Professor Wu asked.

"Okay, so shall we come to your office tomorrow at 9 a.m.?"

"That's great, I'm really sorry to let you come once on Sunday, then I won't disturb your rest, goodbye, Cheng Yin."

"Goodbye, Professor Wu." I put down the phone and picked it up again.

quickly dialed Cui Li's mobile phone, but everyone on the other side of the phone always listened, and it seemed that Cui Li must be asleep. But it's not surprising, it's really tiring today.

I started writing a message on my phone: Cui Li, tomorrow at 9 a.m., Professor Wu asked us to go to his office to discuss the AEF research center.

As soon as I sent the message, I put my phone next to it and fell asleep.

November 21, 2021 at 8:05 a.m

"Thousands of years have passed, and I have never forgotten each other's vows..."

"The years have passed in a hurry, but you are still looking at me, and you have not forgotten our tomorrow..."

My phone's alarm ringtone wakes me up.

I looked at the time, immediately jumped out of bed, washed up briefly, took my coat and ran towards HKUST.

On the way, I kept calling Cui Li. But I still haven't got through, I really don't know if Cui Li has seen the message I sent him.

November 21, 2021 at 8:45 a.m

I finally arrived at the school 15 minutes early, because it was a Sunday and it was still early, so there was no one in the school, and I quickly came to the door of Professor Wu's office.

I knocked on the door of Professor Wu's office, but there was no response, but I could clearly hear a noise inside.

"Professor Wu, Professor Wu, I'm Cheng Yin, can I come in?" I asked, knocking on the door.

But there was no response inside, but I was sure there must be someone inside, right!!

I suddenly remembered the accident of the previous HKUST professor, and suddenly I became nervous.

"Professor Wu, I'm in?" I asked tentatively.

But there was still no response.

I slowly pushed open the door of the office, and suddenly saw the familiar little face holding an envelope on Professor Wu's desk in one hand, looking at me with innocent winking eyes......

"Why are you again? How did you end up ...... here? What are you doing? I glanced at the envelope and asked him.

"I ...... I ......" The little boy touched his head and smiled innocently, then pulled his legs and ran.

"Hey, wait a minute, I'll stop you!"

I kept shouting behind the little boy, but he ran very fast, and in a blink of an eye, he ran out of the school building and through the school gate.

"Stop! I'll tell you to stop! I shouted behind him.

But as if he hadn't heard, the little one turned and jumped onto a bus that was just at the stop. By the time I was trying my best to get to the platform, the car had already driven away.

"You kid...... Run...... It's pretty fast. I gasped.

At this time, I happened to see the campus bicycle placed on the side, and quickly took it and rode the bicycle quickly to catch up with the bus in front of me.

"Little one, you're done! Don't let me catch up with you! "I was desperately chasing after the back of the bus, and I was about to catch up, but the bus was driving right into the tunnel.

The boy grimaced at me triumphantly through the glass window.

"Don't think I'm going to throw in the towel? There are no doors either! ”

I rushed uphill with the front of the car and rode as fast as I could, until I saw the bus speeding out of the tunnel at the other end of the downhill.

I chased the bus all the way, and there were several stops but the little boy was nowhere to be seen. When it finally came to a stop on the other side of a remote sandy beach, the little boy looked left and right for a moment, and finally walked down tremblingly.

"Good boy, I've finally caught you!" Suddenly, I appeared from behind the boy, grabbed him by the collar, and carried him forward.

"How...... How are you? Haven't you been dumped by me?! The little boy screamed and kicked his feet.

"Dump me, you want to be beautiful, say where are your parents? I'm going to let them discipline you well! I said sternly.

"Looking for parents? No, no, don't...... I don't want to look for parents! Let go of me! "The boy kicked me hard in the stomach.

"Damn, you little guy, you have a lot of strength."

Because of the pain, I let go of the hand that was holding the boy.

The boy kept running, desperately running towards the beach.

How did this little boy end up in Professor Wu's office? Maybe he has something to do with Professor Wu. Thinking of this, I couldn't help but pick up my phone and send a text message to Professor Wu, and continued to chase after the little boy.

The little boy had a hard time running in the sand because of his short legs, but I walked to him without much effort.

"How? Throw in the towel, right? Just you little guy, do you still want to run? I'll tell you...... Where are your parents? You take me, I must make them ......" I was about to continue, but the boy clenched his fist and lowered his head very low, as if he was about to cry.

"He won't ...... at all Won't care about my ......"

"What do you say? Who wouldn't care about you? This sudden remark baffled me. But the little boy in front of him could see that he was really sad.

"He wouldn't care about me at all! No! "The little boy suddenly turned his head and yelled at me, and I saw a tear in the corner of his eye." Work, work! After my mother left, he still only knew about work and never cared about me! Do you know how sad I am every night? Crying every day...... Crying every day...... But what about him? I want to marry another woman! I just hate him, and I'm just going to make trouble for him! ”

As he spoke, he shook off my left hand, which I was about to reach, and ran away in the direction of the sea.

The sky suddenly darkened, accompanied by a few thunders, and two or three drops of rain fell on the palm of my hand.

"It's windy, it's going to rain, let's hurry up, or it'll be dangerous." A father lying on the beach took off the sunglasses he was wearing on his eyes, glanced at the sky and said worriedly to the child next to him.

The child also looked at the sky, nodded, and immediately got up and packed his things and ran with his father to the car parked beside him.

"Hey, little one, danger, come back! Come back soon! I shouted anxiously to the little boy in the distance as I ran briskly towards the little boy.

The sea breeze whistled in my ears and blew towards me with a strong wind.

The little boy did not seem to heed my warning, but continued to run alone by the sea......

Suddenly a wave hit and rolled up the little boy's body and pushed him into the sea.

"Ah!!!h

The little boy's screams blew into my ears by the wind, and I just wanted to take off my clothes and run into the sea, but I saw Professor Wu rushing over desperately and throwing off his clothes and rushing directly into the sea.

"Xiaohan, Xiaohan, if you hold on, Dad will come to save you!"

It turned out that the little boy was Professor Wu's son. Fortunately, this may be an opportunity to reconcile father and son. I'm not involved.

Looking at Professor Wu who jumped into the sea in front of me and fought desperately against the sea, for some reason, I thought of the old man and the sea - they are also fighting against the sea, but the difference is that he is standing in the position of a father and trying hard to protect his children.

The wind and rain are a little lesser, and the waves are calmer. I saw Professor Wu walking out slowly with his son in his arms. He fell to his knees with a thud, and I stepped forward to help them up.

"Thank you, Cheng Yin."

I smiled and shook my head.

The little boy coughed twice, spit out the water that had choked in his throat in one gulp, and slowly opened his eyes.

Professor Wu patted the little boy on the back: "Xiaohan, how are you, is there anything uncomfortable?" ”

The little boy looked at Professor Wu in front of him, and at that moment he suddenly howled and cried, hugged Professor Wu hoarsely and shouted: "It's terrible, it's terrible, Dad, I thought I would never see you again!" ”

Professor Wu couldn't help but burst into tears, stroked the back of the little boy's head, and said to him with emotion: "It's all Daddy's bad, it's all Daddy's bad, in fact, Dad works so hard just to be able to go back to the past one day and change the fact that your mother left." But now Dad finally understands that there are some things that I can't accomplish in my lifetime, and Dad just wants to live in the moment and live happily with you and my current lover. You...... Can you stop hating your father? ”

The little boy nodded, and once again vigorously hugged Professor Wu in his arms.

A wisp of purple sun pierced the rain cloud, and it slowly receded, revealing a dark purple gold.

How many days and nights have been accompanied by each other, how many cold and frozen misunderstandings have been embarrassed, how many hatreds and complaints, love and attachment have been exchanged for a piece of the sky before the sunset on the sea?

Professor Wu and his son, the two of them clinging to each other in the remnants of the sunset, crying and crying but laughing

And I laughed, too.

"But how do you know I'm here?" The little boy asked curiously.

"You also have to thank the big brother next to you, it was he who sent a message to tell me that you were here, and I drove all the way here, fortunately, you are safe and sound now, otherwise...... Otherwise......" Professor Wu said, tears streaming from the corners of his eyes.

"I ...... I was wrong......" the little boy said apologetically, bowing his head.

"No, I was wrong...... Professor Wu hugged the little boy, tears streaming down his cheeks.

After a while...

"Kid, shall we go back? All right? Professor Wu took the little boy's hand.

"Good~" the little boy replied happily.

The little boy hadn't walked a few steps before he looked back at me.

"Big brother, thank you."

At this time, Oh suddenly became a little embarrassed.

"By the way, little one, I don't know your name yet."

"Wu Han, my name is Wu Han, big brother, what about you?"

Wu Han...... This, is it the same name and surname? Still is...... A coincidence of fate?

"My name is Cheng Yin."

"Then I'll call you Brother Yin in the future, right?" The little boy said innocently.

"Okay."

In this way, I returned to Professor Wu's car with Professor Wu and Wu Han, and the car started quickly, it was raining heavily outside, but it was very warm inside.

"By the way, Cheng Yin, it's my son's birthday in a few days, Wu Han, I want to invite you to participate, you must come." Professor Wu said, holding the steering wheel.

On Wu Han's birthday, I looked at the little guy in front of me, and my eyes softened.

"Big brother, you must come to participate." Wu Han said with a pitiful expression.

"Good, good, good. As long as you are good, I will definitely come to participate, and I will bring you a gift. I said with a smile.

"Really? That's great! Wu Han shouted happily.

"Cheng Yin, seriously, it's really great that you can participate. It's been a long time since I've seen Wu Han as happy as he is today. Professor Wu was also very happy.

"Then we will make up our minds, you must come." Wu Han clenched his right hand into a fist and stretched out to me.

"Okay, that's a deal." I also fisted with my right hand and gently knocked on Wu Han's fist.

"Professor Wu, then we don't have to ...... today" I suddenly remembered the incident of the AEF Research Center.

"Cheng Yin, forget it today, it's raining so hard, and your clothes are all wet, I'd better send you back first, I'll talk about the research center in two days." After Professor Wu sent me back to my accommodation, he took Wu Han and left.

Just then, my phone rang again. You don't need to look at it to know it's Cui Li.

"Cheng Yin!! I just saw your message. What do you think? Is Professor Wu angry? Is it too late for me to come over? Sure enough, Cui Li on the other end of the phone looked like he had just woken up.

"You're lucky, heavy rain, so it's canceled, keep sleeping, bye." I hung up.

Glancing at the sky.

Wu Han...... Are you that Wu Han?
