"I'm sorry that I haven't been in touch with Yayoi-san during the time before the start of school......"

"That's all you want to say?" Yayoi Akizao looked at him calmly as water.

“……”

Narumi Yu's heart rises in the beginning of autumn, and the heat of summer has not yet dissipated, becoming more and more obvious.

The shouting on the playground had stopped, and it was probably time to rest, and only the chatter remained. In the function building next to the school building, a melody of wind music comes from the music room, mixed with two or three dissonant notes.

The evening sun had not yet subsided, and it spilled into the window obliquely, leaving patches of oblique squares of light and the shadows of the window frames on the pine table.

The bottle of lemonade that had just been opened was also standing in the light spots, and the fine bubbles rising from the bottom of the bottle could be clearly seen through the sunlight. Next to it are about a dozen documents consolidated with thumbtacks, and from the thickness of one or two centimeters, you can see that the student union has a short time to relax on the first day of school......

He pays attention to everything in front of him, in his ears, everything that can pause his thoughts, does not think, does not respond.

Until everything has been heard and seen once, and there is no notability to move his gaze back to the girl behind the desk.

“…… This outfit on you. Not in school today? Yayoi Aki sighed, raised his right hand that was holding the pen just now, his slender and beautiful fingers were slightly bent, his thumb was against his chin, his index finger was propped up under his lips, and he looked him up and down with helpless eyes, and asked.

"After the first class in the afternoon, take a leave of absence to go out ......"

"With Imadegawa-san?"

"Ahh......h Emptying his mind, he followed Yayoi Akizao's question and gave the answer in a wooden manner.

"'A beautiful girl who looks like President Yayoi is not lost at all to Class C of the second grade.' , That's what they said, I guess it could only be Imadegawa-san. ”

Narumi Yu never saw sadness or resentment in Yayoi's early expression, and his tone was no different from that of ordinary small talk.

"Hmm......" Although he felt guilty, Yayoi Akiza's calm and usual tone also made him gradually feel at ease, "It's her." ”

Outside the window, the shouts of the football club calling the names or numbers of teammates were heard again.

"School uniforms?"

"In the Department of Classics."

"So what are you going to do? If it's inconvenient, it's okay if you don't tell me. ”

"It should be said that it is to save people." He gathered his thoughts and told Yayoi Aki about what happened in the afternoon, "On September 1st, at 2:31 p.m., at the intersection next to the Tokyo subway station, a car will lose control and crash into a pedestrian who is crossing the road......"

"Does reality correspond to dreams......" Yayoi Aki glanced at the lemonade on the desk, the pale yellow soda was clear and transparent in the sunlight, "Today in the dream, it's orange soda, there is Shiina-sana next to you, and the topic we talked about is to ask you to dub it." ”

"Even if there are only a few or a few dozen people in the variables, the course of events will be completely different." She retracted her gaze and looked back at Narumi Yu, "For example, do you hear the wind club practicing?" Today in the dream, they are resting. ”

"If I were Imadegawa-san, a more effective choice would be to intervene in the actions of the accident maker in advance, rather than dragging you to the scene of the accident to intercept you."

"So ......" Narumi pondered.

The butterfly effect, the changes in the world line caused by various variables...... It's impossible for Imadegawa Chisaka not to think of this. And the crow that could only be seen from the rooftop could not make him related to the accident in any way.

If you don't know in advance, it's unknown whether this accident happened, so Imadegawa Chisaka must have done an investigation in advance.

And sending a message to him to see the crow at noon, and by the way, adding the rhetoric of "verification success", is it to guide his thinking inertia?

After the investigation, he did not intervene in advance, but chose to intercept the scene more ostentatiously......

"Imade-san has another purpose?"

"Perhaps, you are the one who should care about these things." Yayoi Aki picked up the crepe early and took a bite, "...... Not bad. ”

"It's been a long time."

"And then? After being the Unsung Hero, where did you go? ”

"Ah......h

Finally, he slowly lowered his head and said, "I'm sorry......"

"As I just said, you don't have to tell me if it's inconvenient." Yayoi Akizao watched quietly and said softly.

"There's no inconvenience ......" Narumi Yu cheered up and looked up, "I went for a walk in the park with Imadegawa-san, she left for something, and I bought crepes and went back to school." ”

"Ahh......h

The eyes of the two were met. His eyes, which were as dark as night, were like mirrors, reflecting everything about him.

"It's back again," Yayoi Akiha, who had those eyes, said softly, "the former Narumi-san." ”

The wind section has changed the etude, the melody is soothing and melodious, and any discordant notes cannot be hidden, which requires more cooperation between the ensemble members.

Yayoi's early voice drifted to Narumi Yu's ears with such a melody.

"First, second...... Only the last one was done. ”

"Firstly, inattentive, secondly, indecisive, thirdly, dishonest, secondary, not confident...... Finally, like me. ”

"If the last one is abandoned...... The first four can do it, right? ”

Horn –

The flute of the treble rings out abruptly in the melody, and although it is only for a second or two, it is particularly harsh.

Subsequently, the practice of the wind band was like toppling the first domino, and the mistakes were frequent, and finally I had to stop and adjust.

The world was suddenly much quieter, as if he was forcing him to say something.

"I," he said, ignoring his thoughts.

"In that case, then ......" Yayoi Aki interrupted Yuu Narumi that there was no follow-up character, raised a hand, retracted his thumb, and said to him, "How about trying to forget me?" ”

“……”

"I'm sorry!!!!" The remorseful apology pierced through the windows of the music classroom, resounded throughout the campus, and into the student council room.

Narumi Yu swallowed back a "sorry" that had already come to his mouth.

"We're going to get engaged at Christmas......"

"That's it, congratulations."

"I ......"

"Want a Christmas present? Do you want to congratulate you on your engagement? ”

"No need to ......"

"Do you want me to scold you for being a scumbag and scolding you for playing with your feelings?"

"Not ......"

After an interlude, the wind club practice quickly adjusted and started again. It's just that the high voice is a little thinner than before.

Without a flute note, the ensemble can still play a melodious melody.

"You don't know why, but you feel compelled to tell me." Yayoi Akihaya said in a declarative tone, which gradually turned into a question, "No consideration of making amends, no consideration of redemption, everything depends on time to solve - this is the freedom you have been seeking?" ”
