My Little Sister Suddenly Confessed to Me, but What Am I Supposed to Do by Dating My Little Sister? - Chapter 42 & 43 & 44

Chapter 42: My… Bride?

Midterms passed smoothly, and after the exam break ended, thanks to my sister, my math test came back with an abnormally high score.

During lunch break, I ate my bento with my sister as usual. She joined her friends for chatting while I sat at my desk reading a book. Then our homeroom teacher—who looks like a middle schooler with twin-tails—Shiroi Satomi, commonly known as “Judgement,” came into the classroom.

“Hasemi… Yuu-kun, can you come with me for a moment?”

I was suddenly summoned by my homeroom teacher. Did I do something?

“Suuuure.”

I answered and looked at my sister. She was looking at me, so I indicated with my eyes that I didn’t really know what this was about but I’d be going. My sister seemed to say “I love you” back with her eyes. Well, that’s just my imagination, though.

While thinking such silly thoughts, I followed Shiroi-sensei.

Walking behind her, I fought the urge to mess with her twin-tails that bounced pyoko pyoko up and down. From the front, she’s wearing a suit, so you think “maybe she’s a teacher?” But from behind, she only looks like a student—a middle schooler, even. What is with this teacher? Well, there was a teacher who looked like an elementary schooler in a certain anime, so I guess this is better than that.​

After walking for a while, we stopped in front of a room labeled “Conference Room.”

“Go in, Hasemi-kun.”

Prompted by Shiroi-sensei, I entered. Inside was a not-very-large conference room with two long tables arranged in parallel and about ten chairs.

The teacher pulled out two chairs from in front of the table, set them diagonally to half-face each other, and told me to sit.

I sat down and looked ahead. Shiroi-sensei stared intently at me. I made a confused face and stared back.

We stared at each other for a while, but I finally thought what’s with this person? and spoke up.

“Um… Sensei?”

The teacher’s expression changed to one of realization.

“Ah, sorry. Um, where should I start… um, um, first, this.”

She showed me what looked like some difficult documents in a flustered manner. They had things written on them like “Ministry of Education,” “school education,” “volunteer activities,” and so on.

Eh? What? Is she telling me to join a “service club” or something? The only difference between me and that character is my sister, you know? By the way, my sister is cuter.

“So, what’s this about?”

“Um, well, to roughly explain, our high school also has to do volunteer activities.”

“Volunteer activities?”

“Right, right. So, we have to decide what kind of volunteer work to do, what kind of activities were done… basically, keep it as documentation and preferably continue it going forward. That was decided in a meeting.”

“I see.”

Honestly, I’ve never said I was interested in volunteering. I’m not interested in the first place, and I don’t understand why she’s telling me this.

“Naturally, it would be strange for the school to force students, so the student council decided to take the lead and do it voluntarily.”

The teacher was speaking with slight anxiety. Well, she’s probably young, so this was likely pushed onto her.

“So, Sensei is the student council advisor, and I was entrus—no, asked to handle this job.”

Figured as much.

“However, since we’ve never done anything like this before, we’re in a state of groping around, not knowing where to start or how to do it.”

She seemed reluctant to say the important thing, like something was stuck in her teeth, so I asked directly.

“So, why was I called? I’ve never done any volunteer work or anything.”

“Um, well… together with… um, you’re the only one I can ask, or rather—right, right! You’re not in any clubs or committees, are you, Hasemi-kun?”

“Well, I’m in the ‘Going Home Club.'”

I escaped committees by winning at rock-paper-scissors. My sister almost became a class representative, but the moment she made a troubled face, girls from the class raised their hands one after another saying “I’ll do it instead,” and she was spared.

“So, could you help out just a little?”

Shiroi-sensei turned toward me with her hands clasped in a pleading gesture.

“No, I’m sorry.”

“No good?”

“Yes.”

Honestly, I’m not interested, and it’s too much trouble. Right now, my hands are full with my sister. Lately, my after-school time with her has become precious to me.

But the teacher didn’t give up and kept inviting me.

“I’m sorry, but I’d like to decline.”

“No matter what?”

“Yes.”

I don’t understand why she’s so insistent about inviting me specifically. If it were my sister, that’d make sense, but… my sister?

“Uuuu, uuuu, waaaaaaaahhhhh!”

The moment I was thinking that, the teacher suddenly started crying! Haa? What is this?

“Uu, Hasemi-kuuuuun! Yuu-kuuuuun!”

She put her hands to her eyes and cried dramatically, just like in a manga.

Haa? What? What’s happening?

I had absolutely no idea what was going on. I don’t understand at alllll.

“You said you’d make me your briiiiide!”

“Haaaaaaaaaaaaaaa?!”

I have no idea what she’s talking about. What is this situation? And bride? Mine?

“…Um, Sensei?”

“Waaaaaahhh! You were so cuuute back then—this is awfuuuul!”

She looks like a middle schooler, so it feels terrible, like I’m making a middle schooler cry.

“Um, Sensei, what exactly are you talking about?”

“Hic, hic… So you really did forget about me… even though you said you’d make me your bride.”

Her makeup had run with her tears, and her cute face looked like a panda’s.

No, I remember… hm? That face, where have I…

Then, the teacher pulled out an envelope from a file.

“Hic… Uuu, this… I thought maybe you really had forgotten about me, so… I brought it from home.”

She opened the envelope and took out a letter from inside.

“It’s my… treasure.”

Saying that, she opened the letter and placed it on the desk. There, it read:

“Dear Big Sister, thank you for helping me. I was happy to be helped by a beautiful Big Sister. I love you, kind and beautiful Big Sister. When I grow up, please marry me. I will definitely make you happy. — Hasemi Yuu”

“GYAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHH!”

My lost love letter… had been discovered now, in a place like this…

Chapter 43: My… Bride?

Th-this, this… why? Twin-tails… Ahhhhhhh! That Big Sister from back then was… Sensei?

“Hic… Yeah. You finally remembered? It’s been a while, Hasemi Yuu-kun.”

She called my name while crying. She had rubbed her eyes so much that her mascara had run off. She’d gone past panda and now looked like a criminal with their eyes blacked out.

“Huh? No, wait… why? Ah, I see. Sensei is a graduate of this school.”

I recalled the words I’d discussed with my sister before: “Maybe she’s a graduate of this school?”

Shiroi-sensei began speaking with a smile, as if reminiscing about the past while looking at me lovingly, even while crying.

“That’s right… It’s so nostalgic… On my way home from school, I used to see Yuu-kun playing alone a lot. I thought, ‘What a cute kid.’ Then one day, I saw that Yuu-kun had gotten hurt, and I panicked. Yuu-kun was crying, and I felt so sad too.”

“Blood was flowing from your leg, and I kept saying ‘It’s okay, it’s okay’—that was all I could say. I was just flustered. After a while, someone from the neighborhood who knew you took you home. I couldn’t do anything…”

“I thought you were cute, but when you got hurt, I couldn’t do anything. I was so down on myself for so long. And then, after a while, Yuu-kun appeared in front of me.”

“I thought Yuu-kun would ask me, ‘Why didn’t you do anything?’ I kept apologizing in my heart, ‘I’m sorry, I’m sorry.'”

“But then, Yuu-kun said, ‘Thank you for saying it was okay the other day. Because of you, Big Sister, I was okay.’ That’s all you said, and then you ran off with a red face.”

Shiroi-sensei smiled brightly.

“I was so happy. To be told that… I was watching you run away, and then I saw something fall from your pocket. When I picked it up, it was a letter. The letter said ‘To Big Sister,’ so I thought, ‘Is this for me?’ When I opened it and saw this, I just cried and cried right there on the spot.”

“From that day on, this has been my treasure.”

She touched the letter on the desk as if stroking a child’s head.

“This year, when I first saw the name of a student I’d be in charge of, I was shocked. I thought, ‘Same name?’ But the first time I saw Yuu-kun, I was certain. ‘Ah, this is the boy who gave me this letter. This is Yuu-kun.'”

“I kept talking to you in my heart. ‘It’s me. It’s Big Sister.'”

The teacher gazed lovingly at the letter. After staring at it for a while, her face crumpled again (kushari).

“B-but, that Yuu-kun… uu, that cute Yuu-kun said he’d make me his briiide, but now he won’t listen to my requeeest! Waaaaaahhh!”

It wasn’t fake crying—tears poured down her face, and she started crying again.

Ehhhh, seriouslyyyy?! Wait, I never SAID it—I just WROTE it!

Even though this is a conference room, if someone walked in on this, how would I explain it?

“Ahhhh, fine, I get it, I got it! I’ll help! I just have to help, right?”

“Really?”

Dammit, she’s kind of cute. Wait, how much older is she than me? No matter how I look at it, she looks younger than me.

“Yes, yes, I’ll do it.”

“Uu, thank you. As I thought, Yuu-kun is cute and kind.”

She smiled brightly while tearing up again.

Seeing that smile, I felt a bit embarrassed and looked away from the teacher.

“So, what do I need to do?”

“Um, hmmmm, let’s see… For now, can you come to the student council room with me after school? I’ll introduce you to the Student Council President first.”

The teacher pulled herself together and returned her expression to that of a teacher, but her eyes—no, her whole face—looked terrible. Plus, with her baby face, it hadn’t gone back at all.

The Student Council President… Seriously…

I shuddered in fear, recalling that demon’s face.

Seeing my expression, she said:

“Eh? You know the President, right? She’s kind, pure and elegant, beautiful… Why are you making that scared face? She’s not scary, you know?”

Ahhhh, well, yes, that’s how it appears from the outside…

“Well, okay, I understand. Should I just go directly to the student council room after school?”

“Right. I don’t have afternoon classes, so I’ll go ahead and wait for you.”

By the way, Shiroi-sensei teaches Japanese.

Shiroi-sensei stood up and tried to open the door. I hurriedly grabbed her hand as she reached for the door and held it, saying:

“Sensei, you can’t go out with that face…”

I managed to stop the teacher—whose makeup had completely run off, leaving her face pitch black—before she could leave the conference room.

#######################

After afternoon classes ended, the tension in the class eased during the after-school period. My sister came over to me as usual.

“Let’s go home, Onii-chan.”

When my sister came over to me, everyone’s gazes gathered, but for some reason, lately they felt like warm gazes… Trying not to worry about it too much, I told my sister I couldn’t go home with her today.

“Ah, sorry. I got called for something after school.”

I didn’t have time to explain what happened at lunch since it came down to the wire.

“Eh? By who?”

In an instant, my sister’s eye color changed. Eh? That’s scary…

“Ah, no, look—you saw Judgem—Shiroi-sensei call me during lunch, right? I have to go to the student council room now because of that.”

I didn’t feel any need to lie, so I told her as it was, but:

“Shiroi-sensei… Student council…”

My sister started muttering (butsu butsu), so I hurriedly tried to reassure her that it was fine:

“Um, it’s something about volunteer work led by the student council or something— Heeeey, Shiori-san?”

Just like always, my sister was entering her own world. Is this the first time at school? I thought, when:

“…Shiroi-sensei, beautiful… student council, President beautiful… Onii-chan… Shiroi-sensei… President…”

She started muttering (butsu butsu) even more. It felt different from usual, so I kept calling out to her.

“Heeeey, huh? Heeeey.”

“Onii-chan!!”

I was startled when my sister suddenly reacted and answered.

“Yes.”

“I’m coming too!!!”

“……Pardon?”

Chapter 44: My… Bride?

When my sister said she was coming too, I told her she wasn’t invited, but she stubbornly insisted on going no matter what and wouldn’t accept any argument. Once my stubborn sister gets like this, she won’t budge even with a lever, so I gave up on persuading her and decided to just bring her along.

The two of us walked down the after-school hallway. Passing students heading home and others going to their clubs, we made our way to the student council room. From a distance, we could hear the baseball team’s rallying cries and music from the concert band.

Me and my sister… the so-called honor student and the underachiever (who’s the underachiever?!) heading to the student council room together—I’ve read something like this in a light novel somewhere. Um, do I have to use magic or something?

While thinking such pointless thoughts as usual, we arrived in front of the student council room. Unlike in light novels, I don’t think we’ll be attacked, but I had my sister stand back while I knocked on the door.

From inside, I heard Shiroi-sensei’s voice: “Come in.”

“Excuse us.”

When I opened the door, Shiroi-sensei, who had been sitting in a chair, stood up with a beaming smile.

“Yuu-ku—”

She approached while calling my name like in the old days with a bright smile, but midway, she seemed to notice my sister’s presence and hurriedly froze in place. Perhaps she realized calling me by my first name was inappropriate when my sister was watching?

“Yuu-kun and Shiori-san came too.”

After thinking for a moment, the teacher perhaps reconsidered—since my sister and I share the Hasemi surname, maybe it was okay to use our first names after all? She said this while approaching.

The teacher instantly switched from the way she used to call me when we first met back to a teacher’s manner of address, and returned to her chair as if nothing had happened.

“I’m sorry, my sister insisted on coming, so I brought her along.”

“Oh, that’s fine. I wanted to invite Shiori-san too.”

My sister glared at the teacher with eyes that practically said “Then why did you only call my brother?” but verbally said:

“I’m sorry for intruding.”

While feeling fear at my sister’s tremendous aura(?), the teacher tried to maintain her composure and answered:

“W-well, no one from the student council has arrived yet. Please sit and wait.”

At her invitation, my sister and I sat side by side in front of the teacher.

After that, the three of us made awkward small talk about class when we heard a knock (kon kon).

“Yeees.”

When the teacher answered, the door opened, and in came a short girl with a cute face, light brown short hair, and a headband with a ribbon accent as a focal point.

The moment she saw the three of us, she flinched, her body trembling. Her expression changed oddly, and she hurriedly shifted her gaze away from us to look at Shiroi-sensei’s face. Noticing this, the teacher began introducing us to her.

“These are Hasemi Yuu-kun and Hasemi Shiori-san, who will be cooperating with us on the volunteer project we’ve been discussing.”

Hearing that, the girl with the headband seemed to understand and began introducing herself with a smile.

“Ah, I see. I serve as the student council secretary. I’m Machiya Natsumi, a second-year.”

Understanding the situation, Machiya-san bent at the waist and bowed politely. We also stood up and bowed together.

Then, this time without knocking, the door opened. There stood two beautiful women. One was that familiar golden demon. Today she was in “President Mode,” so her makeup was natural, she wore red glasses, and her hair was not blonde but a slightly reddish long wavy style.

The girl standing behind the President had chestnut-colored hair tied in a braid behind her with a ribbon. Her face was slightly narrow, but it exuded refinement—the image of a pure, elegant young lady. Her figure was slender, so much so that her waist looked like it might break.

The President, who had opened the door, showed a dubious expression for an instant—either surprised that people were in the room or because she spotted me—but at a speed that no one else could detect, she instantly reverted to an archaic smile.

“I apologize for not knocking.”

She placed both hands in front of her, bent at the waist, and bowed her head deeply in apology.

“Um, Aoi-san, these people are—”

Shiroi-sensei tried to introduce us, but:

“Yes, this would be Hasemi Yuu-san, correct? I am acquainted with him.

And that is Hasemi-san’s younger sister. If I recall, Shiori-san?”

Shiroi-sensei looked surprised and asked:

“You knew them both?”

“Yes. I once saw Yuu-san eating alone behind the school building and took the liberty of greeting him. That’s when I learned his name. As for Shiori-san, she is quite famous at school, so I only know her by reputation.”

Uu, eating alone… well, I was doing that…

“So then, Shiroi-sensei, what business do these individuals have here?”

“Ah, right, right. Um, they’ve agreed to help us with the volunteer project we’re doing, so I brought them here.”

“I see. Thank you very much.”

The President expressed her gratitude in polite tones. But that transformation…

At the President’s suggestion that we should introduce ourselves and deepen our friendship, everyone took their seats, and the secretary, Machiya-san, prepared and served tea.

“Then, I shall begin. I am the Student Council President, Nakagawa Aoi. I am grateful that you have gathered here today. With the members here as the core, let us cooperate on this agenda, join forces, and do our best. I look forward to working with you.”

Without breaking her archaic smile, she gave a polite greeting. Is this really the same person as that blonde? Maybe they’re twins or something? (I actually considered that for a moment.)

The President sat down and gave the Vice President beside her a look. The Vice President nodded lightly, stood up, and bowed once.

“I am the Vice President, Ichikawa Mizuki. I assist President Nakagawa. I am inexperienced, but I look forward to working with you.”

Her refined appearance was no different from the President’s, but her gestures had an air of elegance. Comparing her to the President, this one is a complete young lady. The Student Council President looked at me and smiled. Eh? Did she read my mind? Scary!!

“Well then, it’s my turn. As I said earlier, I’m the secretary, Machiya Natsumi. My handwriting isn’t very good, but I’m doing my best as secretary, so please treat me well!”

In contrast to the other two, she had a bright and cheerful image. Since secretaries aren’t actually specialists in writing, I understood she was joking.

“These three are the members of the current student council.”

The President finished saying that, but I had various questions, so I asked.

“Um, is it just the three of you? And you’re all second-years? And all female?”

“That’s correct. The student council President has the authority to appoint members, and if they were upperclassmen, it would be difficult for the President, so I asked the President if Natsumi and I could assist.”

The Vice President answered.

“This school was originally an all-girls school, so even now there are more girls. That’s why the Student Council President has always been female. There have been boys besides the President before, but it seems like it ends up being mostly girls anyway.”

Natsumi continued.

“Now then, would you two please tell us about yourselves?”

The student council members smoothly took turns speaking in perfect coordination. Feeling a sense of formidability, I stood up and introduced myself.

“Um, I’m Hasemi Yuu, a first-year. I don’t know what I can help with, but I look forward to working with you.”

Saying that, I sat down. When I looked at my sister, she was staring at me, but she had a suspicious look on her face. Hey, hey, what are you planning?

My sister stood up, turned toward the Student Council President, and said:

“First-year, Hasemi Shiori. President, why were you patting my brother’s head behind the school building the other day? Do you like my brother?”

I thought she might pull something, but she dropped a bomb right from the start.

Ahhh, I shouldn’t have brought her…
