Cosine nodded and listened to Kong Mingyu again, "Your name is really special, is it because your parents like math?"

Cosine smiled. Kong Mingyu guessed right. His father was a math teacher. On the day he was born, his father was teaching the cosine theorem to the students on the blackboard.

Later, his name became Cosine.

However, he naturally would not say these words to Kong Mingyu.

In this world, his identity is an orphan. He grew up in a welfare center and does not know who his biological parents are. To be on the safe side, he might as well not mention his parents.

"I don't know very well, anyway, I have this name since I remember it."

Cosine changed the subject without any trace, "What about you? Skylantern means Kongming lantern, right? Your parents like Kongming lantern very much?"

Kong Mingyu sighed softly, "My mother likes to do handicrafts. When she was pregnant with me, she specially placed the Kongming lantern and wished that I would be safe after birth."

Cosine nodded, "I can see that your parents love you very much."

Kong Mingyu's speech and temperament, at first glance, is that he came from a family with good family education and a wealthy life.

When approaching the boarding gate, the appearance of Shen Mang and his party caused quite a commotion.

Passengers who were boarding the plane at the next platform recognized that this was the film crew of Summer Heartbeat, and they came over curiously with the mentality of watching the excitement.

"Mr. Shen Mang, Mr. Shang Zhou, hurry up and board the plane."

The director team was afraid that more and more people would come around and affect the order of the airport, so they hurriedly urged Shen Mang and Shang Zhou to board the plane.

Shen Mang took off his earphones, his long eyelashes drooped slightly, and glanced back.

Cosine and the new guest walked at the back. They didn't know what topic they were talking about, and they both had smiles on their faces.

Shen Mang clenched the ticket in his hand, a cold light flashed in his eyes, he pressed the brim of the peaked cap, and walked to the cabin without saying a word.

"Xiaomang, my seat is right next to you, what a coincidence."

After Shen Mang took his seat in the first class cabin, Shang Zhou also put away his luggage and sat down beside him.

Seeing him sit down, Shen Mang raised his eyes and hummed expressionlessly.

"Idol, I'm just across the aisle from you." Lan Qi sat down on the seat on the other side with his bag on his back.

At this time, Cosine and Kong Mingyu also walked into the passage.

Seeing him, Lan Qi quickly waved his hand and pointed to the seat beside him.

"Mr. Yu, sit next to me."

The flight attendant smiled and reminded, "All passengers must take their seats according to the seats on the ticket, please do not change seats at will."

Hearing the flight attendant's reminder, Lan Qi stuck out his tongue and quickly closed his mouth.

Cosine took out his ticket and glanced at it. His seat was not next to Lan Qi, but behind Shen Mang's row.

"It seems that we are very destined to be in the same row."

Kong Mingyu took a look at the ticket, waited for Cosine to put down his backpack, took it naturally, and helped him put it in the luggage compartment above his head.

"sorry to bother you."

Cosine sits by the window. In his last life, since he fell ill, all he saw was a monotonous white ceiling every day, and it seemed like a long time ago to fly. Looking at the runway outside the porthole now, there is an unreal feeling for a while.

The plane began to taxi on the runway, and a huge roar sounded. When the plane went up, Cosine was inexplicably nervous, and couldn't help clenching the armrest of the seat.

"I haven't been on a plane for a long time?" Kong Mingyu seemed to see something.

Cosine smiled bitterly.

"Well, I'm not used to it."

"If you're nervous, you can pinch this."

Kong Mingyu got a blue stress ball out of nowhere, the size was just right to fit in the palm of his hand, and his fingers would sink into it when he pinched it.

Cosine took the small ball and squeezed it in the palm of his hand, and found that it really relieved the pressure.

"Mr. Yu, what are you pinching? Give me a play too."

Lan Qi was sitting next to a strange passenger. He was bored and looked towards Cosine frequently. Seeing that he was playing with a small blue ball in his hand at some point, he immediately became interested.

"Wait, I have bouncy balls of other colors here."

Kong Mingyu smiled, he seemed to be ready, and took out an orange ball from his bag and handed it to Lan Qi.

The plane entered high altitude and began to fly smoothly.

Cosine opened the shutter of the window and looked at the blue sky and the large clouds, and his mood became brighter.

At this time, he heard the gentle voice of Shang Zhou ahead.

"Xiaomang, the temperature here is a bit low, do you want me to ask the stewardess for a blanket?"

Shen Mang was flipping through an English magazine, and when he heard Shang Zhou's words, he lifted his eyelids indifferently.

"No, the temperature is just right."

He flipped through a few pages of the magazine, but he didn't seem to see anything of interest, so he took out the blindfold from his bag and put it on.

Cosine can see the youth's black hair and the small half of his face through the gap in the seat.

He stared at him, lost for a moment.

He suddenly remembered the sleepy young man lying quietly beside him on that rainy night. And the next morning, he heard a noise outside the door, and he was ignorant. When he couldn't figure out the situation, the man reached out and took him into his arms.

He leaned against his warm chest and could clearly hear his heart beating like a drum.

Kong Mingyu's voice suddenly interjected and came in, "Cosine, are you busy with school projects recently?"

Cosine regained his senses and sat up straight, "Well. I've been busy with a natural subject recently, and the preparatory work is over."

"Then what's your plan next. Do you want to study or something?"

"Should be able to take exams."

"Kaobo is good. Do you want to come to our school? Jiangda's psychology ranks among the top in the country."

With a smile on his face, Kong Mingyu looked at Cosine intently, "My doctoral supervisor is recruiting students, and the direction is philosophy and psychology. If you are interested, I can consult for you."
