Haruka Ito will never forget that day three years ago......

At that time, she had just finished practicing the piano and was about to go home, but she saw a glimmer of light in the nearby study room.

Then, when she approached out of curiosity, she saw the famous junior student in the class, Qin Feng, who had a red light in various subjects, packing his schoolbag dejectedly.

"Classmate Qin, why haven't you gone back yet?" She couldn't help but ask.

The boy froze visibly.

"That's, that's ......"

"Hey, astrophysics...... Mr. Qin: Are you preparing for your graduation thesis? Haruka noticed the holographic textbook that the other party had thrown on the table.

"It's just...... It's the final exam. Qin Feng replied with some embarrassment.

"But, but ......," Haruka pointed to the notebook that the boy had not had time to put away, "Your solution is wrong." ”

"Huh?" Qin Feng was stunned, his gaze followed the girl's white and slender fingers, and fell on the test question, "Won't it?" I've done it well...... And it took three days......"

No way?!

He said to himself, and then took it seriously again, carefully re-substituting the formula into the operation from beginning to end.

But in the end, it seems that the boy who only came to the same conclusion, had to cast his eyes on Haruka for some reason.

"Because you've only taken one aspect into account." "In astrophysics, any given layer inside a star is in a state of equilibrium between the thermal pressure (outward) and the pressure (inward) generated by the mass of the matter outside it. ”

"This ......"

"So the star is like a balloon, in a balloon, the gas inside the balloon is squeezed outward, and the atmospheric pressure and elastic material provide enough inward resistance pressure to balance the inside and outside pressure of the balloon. The same is true for stars, whose internal mass provides inward pressure, and the isotropic gravitational field compresses it, making it the most compact shape: spherical. Haruka picked up the pen and rustled on the manuscript paper, "So, the correct solution to this problem should be like this......"

"Ah, I see!" Qin Feng seemed to be enlightened, and it was like a flash of inspiration.

"And this question, which is also wrong......"

"Huh?"

"And here, the correct solution should be like this......"

……

As a result, it only took the girl thirty minutes to completely negate Qin Feng's three-day efforts.

————————————

When I got home in the evening, it was already 12 o'clock in the evening.

Although it was late November, and although it was already late at night in early winter, the heat of the fire during the day did not subside well, but instead turned into a steaming stuffiness, so that the skin of the whole body could feel a burst of discomfort, and I wanted to get into the discomfort of the air conditioner immediately.

For Haruka Ito, this road is what she has to pass every day to and from school, but it is the first time she has passed here so late.

Tonight, after all the mistakes were finally corrected, in order to avoid another futile effort in the little time left, Qin Feng began to humbly ask for advice.

And Haruka didn't have the slightest impatience, and still answered very seriously.

As a result, because the other party's "basic questions like elementary school students" are too cumbersome, and when she finally finished her evening self-study, Haruka found out......

Time has been dragged to the point that it is too late.

"I'm so sorry for delaying you too much because of me." The boy sincerely apologized.

"It's okay, classmate Qin doesn't have anything to apologize for." But the girl didn't mean to blame in the slightest.

However, after all, because the time has dragged on too late, sending the girl home has become a natural option.

Although at first, he was still polite and reserved about this, but after Qin Feng insisted on the reason of "don't let me become a bad boy who lets girls walk at night alone with anxiety, but doesn't even send it away", he finally changed his mind and acquiesced.

After all, that road is still too remote.

There is no evening whistle, no moonlight to cook wine, and even no street lamps, although it is not enough to reach out and lose sight of five fingers, but the silence of the streets, the ghostly beech trees sticking out of the two sides, and the silent shadows of the tall buildings hidden in the distance, still make people feel a little panic.

Especially when the fog peculiar to that dark night spreads faintly......

However, I didn't feel afraid.

Perhaps, it's because there is an extra boy around......

She thought.

It is less than ten minutes from the school to the neighborhood where Ito's family is located.

The two walked silently, neither of them speaking.

The atmosphere also became a little subtle because of this, especially for Haruka Ito.

After all, this is the first time she has sent a boy home......

Feeling that the boy is only one centimeter away from him, he can easily smell the good smell on his body, and occasionally feel the corner of the other party's clothes rubbing the back of his hand.

Easily, I felt a sense of peace of mind that I had never felt before.

"In another month, I'm going to graduate......" Qin Feng took the lead in breaking the silence as if he was a little speechless, "Do Ito-sans have any plans after graduation?" ”

"Well, when it comes to the path after graduation...... the girl replied, "I guess I'll become a doctor." ”

"Huh?"

"What's wrong?" Haruka glanced sideways at him, "Is there anything wrong?" ”

"No, nothing. It's just a slight surprise. The boy hurriedly shook his head, "After all, I thought Ito you were so good at physics, and I thought you would stay in school to teach or go to graduate school or something." ”

"Nope." The girl smiled, "Physics is actually the subject I'm not good at." ”

Belch!

Qin Feng involuntarily wiped the cold sweat from the corner of his forehead.

Although it is the worst side, it shows the holy light like a god, and what kind of despise me to be willing.

"And ......," Haruka continued, "if you become a doctor, you can help more people." ”

"Huh?" Qin Feng was stunned, "Help...... More people? ”

"Hmm!" The girl nodded, "When I was young, I was sent to a church school. ”

"Huh?" Qin Feng, who didn't understand why the other party suddenly mentioned his past, showed a well-deserved sigh.

However......

Qingxiang, who had begun to immerse herself in her story, didn't notice this, and just said to herself: "Because my family is not as rich as Qin imagined." At that time, I had to pay for my brother's schooling, so I had to study in a church school first. ”

This......

Qin Feng couldn't help but be dumbfounded.

"Life in a church school is very hard. Often there is no meat for a whole week. However, I once found out that it was not actually because of the school's financial constraints, because I saw a lot of fresh beef frozen in the kitchen of the cafeteria...... At that time, I did not understand it, because the nuns usually lived the same hard life as us, and it was not until that day that I understood everything......"

……

"On that day, a 7.2-magnitude earthquake struck my hometown of Kanto, Japan, and many people died. After the earthquake, the nuns took us to the relief effort, and I saw them bring out beef that they would normally not want to eat, as well as a lot of elaborate clothes and warm bedding...... Distributed to the children affected by the disaster. That's when I realized what I was saving was for. ”

"Original...... That's right. ”

"But...... But if you say that...... Even so, it's not enough......"

"Huh?"

"Because I found out that the children who were affected by the disaster, the children who were my age, didn't need beef or clothes and bedding the most...... What they need most is medical treatment and first aid, because of the shortage of medicines and the over-busyness of medical staff, many people die quietly because they can't take care of them. At that time, I looked at a child who was a year younger than me, and her arm was broken by the falling ceiling, and when I divided her clothes, she still grabbed me, crying and shouting and begging me to help her tie up her broken arm......"

"Uh......"

"At that time, I really felt that I was so useless, so useless...... The kind of person who wants to do something for them but finds that he can't do it...... That deep feeling of powerlessness is the most annoying. So from that time on, I wanted to become a doctor, so that I could help more people and ...... With my own efforts, I don't let myself see that sad expression anymore. ”

Haruka said, with a self-deprecating wry smile: "Alas...... Think about it, I'm really very troublesome.,Very willful girl.,No matter who is unhappy, I hate it.,No matter who will show a sad look, I don't want to see it...... Huh? What's wrong with you? Classmate Qin? ”
