[Touken Ranbu] function

Triangular function

Summer vacation is coming soon.

The electric fan on the top of the head was finally repaired under the strong request of everyone, but it seemed that it was not completely repaired because it was approaching the end of its service life. It was like an old man dying, creaking in circles It creaked.

Probably everyone is happy to see the arrival of summer vacation, but it is not the case for me.It means that Tsurumaru and I won't be able to see each other like this every day for more than a month.

Tsurumaru didn't seem to care too much.As always, he scares me in different ways every day, occasionally pulls me out to eat ice cream, and study the finale together-but in the end he will always be teased by him and laugh wantonly with him.

Since there is a holiday, the final exam is naturally inevitable.Before entering the examination room, Tsurumaru was still muttering that he wanted to surpass me, his swearing appearance made people laugh, but he was really worried that he would pass me.But not long after the report card was posted in the corridor, my name was still at the top of the list, and Tsurumaru was aggrievedly ranked No.2 by a few points.

"Sure enough, I'm still a bit unwilling..." He said so on the way home, his too long hair swaying as he walked.Our destination was the subway station, and the packed suitcase trailed behind him, its wheels gurgling across the ground.

"No.2 is also very good? And if one day you surpass me, you can treat me to dinner." I can still chat with him in a calm tone, but in fact I have already been oppressed by the upcoming separation Almost out of breath.It's okay, I said to myself, even if I can't see each other, I can call or text, just like all the long and short vacations in the past three years, Tsurumaru will not let me spend the whole summer alone... probably.

You can already see the subway station.Tsurumaru walked in quickly, and the cold wind from the air conditioner rushed towards his face, easily and quickly relieving the impatience and irritability caused by the high temperature.Tsurumaru watched me thoughtfully unbuttoning the top button of the short-sleeved shirt, and suddenly said "wait for me" before leaving his suitcase and staying where I was.

Taking advantage of Tsurumaru's absence, I turned on the phone screen and sent a text message to my mother, basically saying that I would be home soon.

The side of his face was caught off guard.I turned my head to look, and it was indeed Tsurumaru. He was holding a can of ice-cola, looking at me with a smile, and asked, "Are you scared?" as usual.He pulled the tab of the Coke and handed it to me, saying, "It's been a long time, I'm going to buy a drink because it's very hot."

The cold carbonated drink slipped into the throat, stimulating the drowsy brain to wake up, and immediately refreshed.Tsurumaru seemed to subconsciously want to hold my hand like before, and then pull me to buy a ticket, but suddenly realized that I had Coke in one hand and luggage in the other, so the raised hand froze in the air, unable to move Put down traces.

"Let's go, Xiaoyi, let's buy a ticket."

"Wait a minute." I said, drank the Coke in my hand as quickly as possible, wiped a line of Coke that inevitably slipped down my chin, threw the can into the trash can next to it, and took the initiative to hook it. Tsurumaru's finger.Tsurumaru was stunned for a moment, but it was only for a moment, then he raised his beautiful eyebrows like countless times in the past, and his white and slender fingers wrapped around mine even more tightly.

It makes me feel a little more at ease.Tsurumaru Kuninaga is right here, half a step ahead of me, walking at an unhurried pace, so close that I can clearly describe the gully on his short-sleeved shirt. The sense of security that comes from.

Tsurumaru pulled me through the ticket gate one after the other after buying the ticket—he let go of my hand reluctantly, and held it again after passing the ticket gate, this time he chose to put his finger Squeeze into my fingers one by one, and then gently buckle.We waited for the subway on the platform.He still didn't let go of my hand, he smiled and greeted the classmates he met while hooking my fingers, occasionally curling up his thumb, scratching his fingertips on my palm until the tip of my heart.

No matter how much I prayed, hoping that the subway would arrive a little later, it still arrived as scheduled, and the door slid open silently.Not many people got off the bus, so the compartment was a bit crowded.Tsurumaru thought for a while, then pushed me to the wall of the carriage, with his hands resting on both sides of my head, his slender figure blocked the crowded flow of people.I breathed a sigh of relief in the small space separated by him, and didn't even dare to look up to see what his expression was now when I was thanking him-but I could imagine that it must be with silvery white eyelashes hanging down, pursing his face He raised his light-colored lips, curled up the just-right playful arc at the corner of his mouth, and asked in a low voice, "Are you scared?".

Luckily I didn't have to hold on for long.As the subway gradually approached the terminal, the number of passengers in the carriages dwindled, and the few remaining people were still familiar.Tsurumaru and I sat down on the vacant seat, and the sore muscles in our arms were relieved at the same time.

"It seems that there are quite a few acquaintances—Xiao Yi, the one over there is Taiko Zhong Zhenzong, a junior." Tsurumaru smiled and pointed to a boy with a childish face, then turned his fingers in another direction, He clicked in the void, "Here is Mikazuki Zongjin, a strange person who always laughs 'hahaha'. Well, I can recognize him without introducing him, right?"

I nodded, because that Sanriyue's appearance was indeed very delicate, even if I didn't ask about it deliberately, I would still remember that there was such a person when I listened to the girls in the class chatting every day.

Tsurumaru said that there are many acquaintances, but he didn't go over to say hello, but called the other party's name to attract the attention of the other party and waved from a distance.

"Senior Crane! We met here unexpectedly—ah, do you mean that you are Senior Sakuichi?"

"Oh, it's Tsurumaru, so this must be Sakuichi. It's the first time we meet. I'm Tsukami Munekin."

I don't bother to find out why all of Tsurumaru's friends know me, so I responded to them one by one with a stiff smile, and at the same time silently counted the rest of the stops in my heart—Tsurumaru will be there soon.

But when he actually arrived at the station, Tsurumaru sat beside him instead, and didn't even have the intention to get up.Could it be that he didn't realize that he had arrived at the station?Thinking about it like this, although I was a bit reluctant, I still poked his elbow: "Tsurumaru, it's here—"

"—Xiaoyi, let's go out to play together during the summer vacation? I'll take you to the video game hall." Tsurumaru interrupted me suddenly, talking about irrelevant things in a cheerful tone.I was so anxious that I couldn't help tugging on his sleeve: "Compared to that, stop--"

But Tsurumaru still didn't respond. Even when I stood up and pulled him, he sat there like a shameless man, refusing to move. The car door was already closed. I sat down in frustration and sighed.

"I'm so scared, do you want to drive me away like that? I will be very hurt." Tsurumaru waved his hand, "Oh... I want to accompany you home and walk back."

"Huh? Why?"

"Don't be so surprised, hasn't Xiaoyi done this before?"

Ah, I forgot if he didn't tell me.Indeed, there have been similar things.Because there are two sites between my home and his home, it's not too far away.So when I used to go home from a long vacation, I used to lie to Tsurumaru that I had to get off at this stop as well, and walk with him to his door, say goodbye and walk two stops back home.

This can be regarded as a secret, and it is a secret that absolutely does not want to be known.After saying goodbye, we walked home under the golden-red sunset. Although we spent more time and didn't spend much time together, we were still very satisfied in our hearts.It seemed that it was just the waving gesture that Tsurumaru made when saying goodbye, and it easily hooked my mind.

The place where he lives also has a small yard, with a wall surrounding a small patch of neatly manicured grass, and a bicycle is parked next to the house.The house had two floors, and I think his room was the one on the second floor covered by white curtains.Judging by Tsurumaru's personality, it would probably be a relatively neat and simple room.But he usually lives in the dormitory, so he should have collected a lot of dust—on the way home, I would think about such things endlessly, which are trivial but always make me happy.

"...how did you know?" I asked with my forehead in embarrassment, Tsurumaru didn't seem to think anything was wrong, and answered me in a normal tone: "I went out with you before, you drank alcoholic drinks and then Just drunk—it really scared me at the time? Then I was going to take you home, so I used your mobile phone to call your mother, and she gave me the address."

I covered my face. Since I was discovered, I couldn't hide it. How would this kind of behavior be thought of...

As expected, Tsurumaru did what he said, and walked with me to the door of the house after getting off the car.After saying goodbye, I stood on the steps, took out the key to open the door, and when I opened the door and was about to go in, I turned around in a strange way.Tsurumaru was still standing outside the wall and did not leave. When he saw me looking back, he smiled and waved his hand, and made a few mouth shapes at me - next, next time, see you, I read it out, next time means When?

I went in, closed the door, took off my shoes, and shouted, "Mom, I'm home."

-------

I tugged at the collar of my bathrobe in the mirror to make sure that I looked well-dressed and there was nothing wrong with it. Before I set off, I walked quickly to the window and took a look. A white figure hidden in the night was facing my window, slanting Leaning on the iron fence of my house.

I went downstairs as fast as I could, took out a pair of clogs from the entrance, kicked them on indiscriminately, opened the door and trotted out.

"Sorry for being late, how long have you been waiting?"

"I've just arrived too. Compared to this, let's go." Tsurumaru smiled and stretched out his hand to pull me.The bathrobe he was wearing was indeed white, and the wide cuffs hanging down revealed a small section of slender arm.I haven't worn clogs for a long time, and I slowly got used to them after walking a certain distance.

The place where the summer festival is held is very conspicuous. If you look at it from above, it is estimated that it is a bright light made up of lanterns.Tsurumaru bought a fox-like mask and pinned it on the left side of his head, and then asked me which mask I liked better.

This is a very common summer festival.We wore similarly designed masks, ate sticky candy apples, shared a box of takoyaki while sitting on curb steps, played multiple shooters for the prize game console, and got splashed while fishing for goldfish Then they looked at each other and smiled.Submerged in the crowd, we are two ordinary tourists, laughing and laughing at the end of summer vacation.

After we finished eating ramen at a well-received shop, Tsurumaru wiped the corners of his mouth with a tissue, then pulled me away from the summer festival venue and walked to a secluded place.I followed him, and I could vaguely recognize that it was a small hill not far from the venue, and I knew it right away—it was the finale of the summer festival, and it was perfect for watching fireworks here.

"I came here to watch the fireworks, thank you for finding it." I said, looking at Tsurumaru's smiling side face.What kind of blessing did he receive from the Creator to be born so perfect and beautiful that he could easily attract everyone's attention without much effort.

Tsurumaru hooked my finger and said, "I guessed it, I wanted to give you a surprise."

It seems that the aggrieved and elongated tail is covered by the sound of fireworks bursting. Those fireworks outline flowers of different colors in the night sky, blooming briefly but beautifully.This is the moment they have been waiting for, completely burning their lives amid the admiration of the people.Those brightly colored rays of light poured into Tsurumaru's golden pupils and melted into a darker lake.

Tsurumaru squeezed my palm.At the same time, the fireworks at the end of the festival were also in full bloom, blowing all the thoughts in my head into a ball.I can't describe the feeling, like the question that I have been wondering for a long time has finally been answered, and it seems that the secret feelings that have been suppressed have finally been answered-looking back after a long time, I think it was just a day when the sun was just right. There was the sound of flowers opening.

I like him, Kirihara Sakuichi likes Tsurumaru Kuninaga.This is the answer I've been looking for.

Compared with the evaluation calculation of trigonometric functions, those deformation and simplification problems accounted for more.This requires memorizing a lot of deformation formulas.When I was bored, I used a pencil to write down neatly in rows on the desk. The newer handwriting later was not a mistake but a deliberate correction.There is a line at the bottom of all formulas, which does not belong to half-width double-angle, nor does it belong to sum-difference product.Not even the formula, but I never wiped it off.It was written by Tsurumaru together at the time: sin Tsurumaru Kuninaga = cos Kirihara Sakuichi.
