“I won’t tell Gu Beilu.”

　　Yu Xi repeated it, looking very serious. Although he didn’t know why the boy was hiding in Gu’s house, it should be related to Gu Beilu.

　　As soon as he noticed the boy let go, Yu Xi quickly and cleverly pulled back the fin.

　　The flannel was a little wrinkled. He pouted his little face and stretched out the wrinkles of the fin, thinking that this kid was really strong. It was his first time to wear clothes, and he liked this shark jumpsuit very much.

　　The boy stood there with an unhappy expression on his face. It was a long time before he asked.

　　”Do you know Gu Beilu?”

　　Yu Xi was concentrating on fiddling with the fish’s fins, and answered honestly, “Not yet, but my parents already know his parents.”

　　The two adults were chatting in the living room.

　　The boy solved his doubts, but became more worried.

　　Once the parents knew the child, it would be even harder to keep the secret. He didn’t know this little shark, and although he looked cute, what if he was a snitch?

　　He looked at Yu Xi who was concentrating on fiddling with the fish fins, thought for a moment, and asked, “Your parents are in the living room, why are you not playing in the living room and coming to this swimming pool?”

　　Yu Xi did not realize the seriousness of the problem.

　　He raised his head and told the boy everything, that he had seen the swimming pool and wanted to go in for a swim, but he would not take off his clothes.

　　The boy listened, his face suddenly fell: “You come to swim by yourself?”

　　Knowing that Yu Xi wanted to swim by himself, it made him inexplicably angry, just like when he saw someone holding a large medicine box just now.

　　Even he himself did not realize how harsh his tone was.

　　”Didn’t your teacher tell you that children can’t swim alone without an adult?” It is very dangerous for children to go into the water without supervision.

　　”You will drown.” He felt that it was not enough, so he added.

　　Yu Xi realized that he was no longer a mermaid. Swimming was no longer as natural to him as breathing.

　　”Oh, yes, I forgot…” He muttered and lowered his head, putting his hands behind his back guiltily, like a child who had made a mistake.

　　Although he was not familiar with the land, he knew that safety was no joke.

　　He heard the boy say again: “If the teacher finds out that anyone went to the swimming pool without permission, he will name and criticize the whole class.”

　　”He’s out of swimming lessons for the entire semester.”

　　The boy just said the last sentence casually. After all, he was not in the first grade yet and had no formal swimming lessons.

　　But when Yu Xi heard this, he imagined himself not being able to swim for half a year, and his eyes immediately turned red with grievance.

　　Not being able to swim for half a year… This is too cruel for a mermaid. Even if he is a human now, he can’t stay out of the water for such a long time.

　　The human world is really so strict. The more he thought about it, the sadder he became. His nose felt sore and tears welled up in his eyes.

　　This time it was the boy’s turn to be stunned.

　　The little shark in front of me had its head lowered and its eyes red, as if it had just been bullied.

　　He didn’t cry when I yelled at him just now, but now he’s about to cry when I talk to him nicely.

　　It’s not like he hasn’t seen other children cry before. He gets annoyed when others cry, and just wants to drive them away so that he won’t be annoyed.

　　But when he saw Little Shark’s tears were about to fall, he actually felt a little panicked.

　　”Why are you crying?”

　　”Don’t cry. I didn’t say I would tell the teacher.”

　　He had never comforted a crying child before, and he didn’t know what to do for a moment. He could only give orders as usual.

　　He is the monitor in the class and always talks to others like this.

　　When Yu Xi heard that he didn’t tell the teacher, he sniffed, suppressed her sourness, and looked up at him.

　　The boy was relieved to see that he had stopped crying: “Stop crying, let’s make a trade.”

　　Yu Xi rubbed his eyes: “What exchange?”

　　Although his tears had stopped, his nasal tone still revealed his grievance.

　　Subconsciously, the boy spoke in a much lighter tone, as if he was afraid that if he continued to be serious, the little shark would start crying again: “I won’t tell anyone that you went to swim by yourself, and you can’t tell anyone that I’m here today.”

Yu Xi thought about it and nodded obediently. He had just promised not to say anything, and he would do what he promised.

　　He couldn’t wait to stretch out his little finger to make a pinky promise.

　　The pinky promise means that the agreement is effective, so no one will know that he wanted to go into the water without permission today, and he will not be banned from swimming.

　　The boy looked at his little finger in front of him and hesitated to move. He had never done such a thing as a pinky promise before, it was too childish.

　　But looking at the little shark’s expectant eyes, he still stretched out his hand.

　　Yu Xi excitedly hooked his finger. Now he wouldn’t be unable to swim for half a year, this exchange was quite cost-effective, he was very happy.

　　The two human cubs breathed a sigh of relief after reaching the first secret agreement in their lives.

　　The boy found that Yu Xi’s hands were actually smaller than his, much whiter, and softer. He even felt that they were not of the same species. He now felt even more that this little shark must have been transformed from marshmallows.

　　After releasing his fingers, Yu Xi’s gaze fell on the boy’s wound again.

　　”Derek, let me help you disinfect your wound. I learned this from the nurse.”

　　The boy was a little confused. He thought it was unnecessary for such a minor scratch… But this time he only hesitated for a moment and did not refuse. He bent his knees cooperatively.

　　They had already made a pinky promise, so it wouldn’t be a big deal if they touched each other’s knees. It took him only a second to convince himself.

　　Seeing that the boy no longer resisted, Yu Xi happily and carefully opened the first aid kit and picked up the alcohol and cotton swabs in an orderly manner.

　　The boy looked at his skilled movements and felt very strange. How could this little shark know all this? This was what his housekeeper and family doctor did.

　　”It may be a little painful, just bear with it.” Yu Xi imitated the nurse’s words. He knew the wound would hurt, and he cried every time. But he couldn’t stop disinfecting just because it hurt.

　　Yu Xi thought about it, put down the things in her hands, and gave the furry shark tail on his clothes to the boy.

　　”If it hurts, just pinch it hard.” When he was afraid of pain in the past, the doctors and nurses also let him pinch the seaweed doll in this way.

　　A shark tail was stuffed into the boy’s hands without him noticing.

　　His mother had bought him pajamas like this before, but he thought they were childish and didn’t wear them.

　　But this tail is surprisingly soft and elastic, and it feels very nice to touch.

　　While Yu Xi was not paying attention, he touched it several times.

　　It was just a minor skin injury, and Yu Xi’s movements were very light and fast. He only touched it lightly two or three times and a Band-Aid was put on the wound.

　　”Okay, don’t touch the wound. Your parents will change the dressing for you when you get home tonight.”

　　Yu Xi closed the medicine box and asked, “Do you live in this community too?”

　　The boy nodded and stroked his tail again.

　　The next second, Yu Xi stood up, and the tail was pulled out of his hand.

　　boy:……

　　Seeing Yu Xi about to pick up the huge first aid kit again, the boy quickly took the lead and asked Yu Xi to wait for him there while he carried the box back to its original place.

　　When the boy returned to the locker room, Yu Xi was walking out.

　　He ran over quickly and grabbed the person: “Where are you going?”

　　Yu Xi said: “I have to go back, otherwise my parents will come looking for me.”

　　The boy subconsciously wanted to keep the boy, but after thinking about it, he found no reason and had to let go.

　　Yu Xi asked again: “Why don’t you go home?”

　　”I’ll go back if you go back first.”

　　Yu Xi waved his hand and said goodbye to his new friend happily: “Goodbye Derek.”

　　The boy said, “You remember we made a hook.”

　　Yu Xi nodded vigorously twice, and the ahoge on his head shook.

　　”Of course I remember, we are already friends.”

　　Watching the little shark’s back slowly running away, the boy stood there in a daze for a long time.

　　At lunch time, the housekeeper was about to go out to pick up the young master, but unexpectedly the young master came back by himself.

　　After Gu Beilu entered the room, he glanced into the living room and found that both his father and mother were at home, but there was no one else in the living room.

　　Mother Gu seemed to be in a very happy mood: “Are you back? Did you have a good time with the kids today?”

　　Gu Beilu is a child with high IQ, but the kindergarten teachers complained that he was not sociable and did not play with other children. That is why they ordered their son to participate in group activities with other children regularly.

　　Gu Beilu walked towards the living room with no expression on his face. The adults seemed normal, and he felt relieved.

　　Father Gu drank his tea, looked at his son and asked, “Are you going tomorrow?”

　　Gu Beilu refused without even thinking: “No.”

　　He didn’t go today. They had agreed to play once a month, and there was no way he would give in.

　　”Oh, the young master is injured?” The butler at the side finally found the Band-Aid on his knee, and nervously asked the servant to get the medicine box immediately.

　　Gu Beilu lowered his head and kicked his legs, only to find that Yu Xi had chosen a cartoon band-aid with a small smiling sun face on a yellow background. It was as cute as a little shark.

　　He never liked cartoon clothes and shoes, but this time it was different.

　　Gu’s father and mother looked at each other, and they saw a hint of smile on their son’s face. Although it was only for a short moment, this kid had never liked to smile since he was born.

　　It seems that he still needs to interact more with people of his age.

　　When they found out that a sum of money for lessons had been deducted from their account last night, they knew that Gu Beilu was up to no good.

　　This morning, they watched the surveillance of the swimming pool on their mobile phones and found that Gu Beilu and Yu Xi had been playing for a long time. Although they couldn’t hear what the two little guys were saying, this was the first time that Gu Beilu was so patient with others.

　　It seems that he likes Yu Xi very much.

　　When the housekeeper took the medicine box from the servant, Gu’s mother smiled and said, “It’s okay. Children are bound to get bumped into while playing. It’s okay if they get a little skin broken.”

　　The housekeeper looked at their young master worriedly: “Then young master, I will change your medicine after you take a bath.”

　　Gu Beilu refused: “No need to change, I’m not injured, I’m just playing with it.”

“Playing close together?” The butler had a look of disbelief on his face, and even suspected that Gu Beilu had been replaced by the young master of the Yu family.

　　Everyone knew that their young master had a serious mysophobia and would never stick anything on himself. Once, a child stuck a small sticker on Gu Beilu, and Gu Beilu scolded the child so much that he cried on the spot.

　　”I said it was just for fun.” Gu Beilu didn’t want to continue this topic, so he turned around and ran upstairs, fearing that the adults wouldn’t believe him and would have to open his wound to see it.

　　In the evening, Gu Beilu asked the housekeeper abnormally where the animal pajamas had gone. The housekeeper showed an incredible expression for the second time that day.

　　”Master, what do you want that for?”

　　Gu Beilu felt that the housekeeper must be getting old and was becoming more and more weird.

　　”My pajamas, can’t I wear them yet?”

　　Butler: “Yes, yes, I’ll ask them to get it for you right away.”

　　Before leaving the room, he looked back every few steps to examine Gu Beilu. He was definitely their young master…how come he looked like him and yet didn’t look like him?

　　After taking a shower, Gu Beilu stood in front of the mirror in silence for a few minutes wearing a dinosaur jumpsuit.

　　This dress is not as stupid as I thought.

　　But if Yu Xi wore it, it would be more suitable.

　　As he thought about it, he grabbed the dinosaur’s tail and squeezed it, thinking that he should have a few more sets of this.

　　Gu Beilu was a very punctual elementary school student who reviewed his lessons at 7:30 every night. Normally, he could get into the state in a second, but today, the electronic clock on his desk had jumped to 7:40, and he still couldn’t concentrate.

　　After several failed attempts, he silently opened the drawer and took out the diary.

　　It is called a diary, but in fact it is his daily plan and schedule. Every night he will tick off the items he has completed.

　　He took out a pen, added “Meet the Little Shark” in neat handwriting, and then ticked it.

　　*

　　At nine o’clock in the evening, Gu’s mother came into the room with a glass of milk, and she almost didn’t recognize that the man wearing dinosaur pajamas was her son.

　　But she could tell at a glance that this was the same style as little Yu Xi’s. She was envious of Yu Xi this morning because he was so well-behaved and cute, unlike her own little old man, who had a 6-year-old body but a 16-year-old mind…

　　She put down the milk and pretended to be confused: “Derek, didn’t you complain that this outfit was too childish last time?”

　　Gu Beilu stared at the book, holding the dinosaur tail in his hand, without looking up: “A 6-year-old should act like a 6-year-old.”

　　Father Gu often used this sentence to educate him.

　　Mother Gu looked at the introductory programming textbook in front of him and rolled her eyes.

　　I would believe it if you were reading a fairy tale book.
