My Little Sister Suddenly Confessed to Me, but What Am I Supposed to Do by Dating My Little Sister?

Chapter 30: Sibling Date

From Yakuo-in, we just kept walking toward the summit.
It might be a “low” mountain, but it’s still a mountain. My thighs were getting tight, and sweat was starting to bead on my skin.
“Hey, Shiori, maybe we should let go of hands…”

“Ah, look, Onii-chan! Yellow flowers!”

“Shiori, you’re trying to dodge the subject, but it’s not working at all. I’m tired of pulling you, so I’m letting go.”

“Then I’ll pull you this time!”

She stepped in front of me and started tugging with surprising force. See, you weren’t tired at all!

“Okay, okay! We can keep holding hands!”

“Yay!”

“Yay” my foot. If the Student Council President or Shiori’s friends see us again…
I looked around nervously.

“What’s wrong?”
“No, it’s nothing.”

Surely they aren’t here. This isn’t another foreshadowing flag, right? (Probably not.)

“Onii-chan, are you talking to someone?”

Enough with the meta comments. After walking for about 20 minutes, we arrived at the summit plaza.

“Waaaaaaaaah… it’s packed with people…”

“Yeah…”

“There’s nowhere to eat our bento…”

“Yeah…”

The summit of Mt. Takao was overflowing with people.

“Pu… fufufufufufu.”

“What is it?”

“I was just thinking, whenever I go out with you, Onii-chan, something always happens.”

“Ah… you’re right.”

“But it’s super fun! We made another memory, didn’t we?”

“Yeah…”

“Onii-chan, you’re only saying ‘Yeah’!”

“Yeah… ah, sorry, sorry.”

My sister walked on, laughing “fufufufu.”

“Ah… Onii-chan, look! Cherry blossoms!”

“They’ve fallen a bit, but they’re still blooming.”

“Beautiful…”

We gazed at the cherry blossoms for a while. Even though it hasn’t even been a month, memories with my sister—different from before—are piling up. My feelings for her are drifting down and accumulating in my heart, just like these cherry blossom petals.

“Ah, Onii-chan! That bench just opened up!”

I chased after my sister as she ran, and we sat on the bench for lunch time.

“Umm, I made onigiri, karaage, and tamagoyaki!”

“Heee, that’s amazing.”

Besides that, there were cherry tomatoes and lettuce, adding nice color.

“Let’s eat then. Itadakimasu.”

“The onigiri filling is… ooh, salmon! Yummy, yummy. The karaage is seasoned well too, delicious. And the tamagoyaki… whoa, this is super good!”

My sister was staring at me blankly.

“Shiori, aren’t you going to eat?”

“Ah, yeah! I’m eating. Itadakimasu!”
She put her hands together while holding her chopsticks, stuffed her cheeks with onigiri, and ate the tamagoyaki.

“I’m still losing…”

“Hm? Losing at what?”

“Nope, nothing! Eat lots, Onii-chan!”

We finished eating and gazed at the scenery.
“Ah… look, Onii-chan! You can see Mt. Fuji!”

“Ooooooh.”

“Next time, I want to climb Mt. Fuji.”

“Isn’t Mt. Fuji tough?”

“Seeing the first sunrise of the year with you would be nice…”
She stared at Mt. Fuji dreamily.

“Well… someday.”

“Yeah.”

Thinking it was time to head back, we descended, taking the lift again to enjoy the view.
The scenery on the way down was beautiful, and my sister was even more excited.

Date at Mt. Takao complete. On the train back:

“That was fun, Onii-chan! But… this was basically like coming here to entertain me.”
“Eh? Well, if you enjoyed it, isn’t that fine?”

“Hmm… then it doesn’t count as going where you wanted to go, Onii-chan. It just means we went where we wanted to go.”

I have absolutely no idea what she’s trying to say…

“I really want you to take me somewhere only you want to go. Isn’t there anywhere?”

“Ehhhh… where would that be?”

“If it’s where you want to go, I’ll go anywhere! Sofap, Mesan-oh, Man*rake!”

“……”

Could it be…? Did she want to go?
To an otaku shop…

Chapter 31: The Blonde Beauty

On the final day of Golden Week, after being dragged around by my sister or forced to keep her company at home for one reason or another, I was finally set free.

“She complained about me tying her down, but we ended up spending almost the whole time together. Well, it was fun, so I guess it’s fine.”

My sister probably couldn’t turn down her friends’ invitations forever, so she had reluctantly headed out today. I thought about just relaxing at home, but I felt like doing a bit of shopping, so I made my way toward the bookstore.

There are some books you just can’t buy when your sister is with you, after all…

At the bookstore inside the station mall, I purchased the kind of books destined to be stored under a mattress and stepped out with a satisfied look on my face. As I passed the ticket gates to head outside, I saw a familiar figure walking toward me from the station.

A gal with long blonde hair, bright red lipstick, an ultra-mini red bodycon dress, high heels, and a designer bag smirked the moment she saw me.

“Oh, it’s been a while.”

“P-P-Pre—” The moment I started to say President, she pressed her hand against my lips, a smile reaching only her mouth.

“You mustn’t say that, boy.”

“Mmph-fkay.”

I gave my muffled response while she held her hand there.

“Perfect timing. My boyfriend flaked on me at the last minute, so I’ve got time to kill. Come with me for a bit.”

“Uh, wait, where to?”

“To get tea, obviously. Or would you rather go somewhere we can ‘rest’?”

“Ah, no, either is—”

“You. Are. Coming. With. Me.”

“Yes, ma’am…”

I was escorted to a certain famous coffee shop a short walk from the station—the kind that automatically serves a side of beans when you order coffee. We sat in the back and both ordered hot coffees, which arrived along with the beans.

Until the drinks were served, the blonde beauty was silent, or rather, she was preoccupied with her phone. So you drag me here just to ignore me? I see how it is…

“U-um, so, did you need something from me?”

“Not really. I just had a gap in my schedule, so I’m killing time?”

“I mean, even if you say ‘killing time’…”

“What’s with that? You should be happy to have tea with such a fine woman.”

She really just said that…

“You’re. Happy. Right?”

“Ah, yes.”

The blonde beauty went back to silence, adding sugar to her coffee and clattering her spoon around.

“So, what should I call you?”

“Whatever you like, isn’t it?”

“In that case, Kaicho.”

Before I could even finish the word, she flicked her spoon toward me, sending a few drops of coffee flying at my face.

“Hot, hot, hot!”

I hurriedly wiped my face with a wet towel.

“What if you’d burned me!”

“Shouldn’t you be glad it was only a burn?”

She said it without a hint of remorse.

“So, what should I call you? Is ‘you’ okay?”

“Just use my name. No one will ever find out anyway.”

If no one will ever find out, wouldn’t Kaicho be fine too? I thought. Then I realized—wait, what was her name again? I think it was—

“Did you forget? It’s Aoi. A-o-i.”

Right, Aoi. If she marries someone named Aoi, she’ll be Aoi Aoi. Alright, I’ve got it.

“So, Aoi-san, I heard you got stood up. Massive LOL.”

I mean, how are you holding up, Aoi-san?

“I’m really going to do it to you.”

“I wonder how you’d even spell ‘do it’—wait, sorry, my inner thoughts and my polite voice got swapped.”

Aoi let out a sigh, took a sip of her coffee, and then let a smile spread across her face.

“Heh, you’re pretty interesting. There aren’t many people who take that kind of attitude with me.”

I resisted the urge to be entranced by that smile, popped a bean into my mouth, and asked a question while trying to look tough.

“So, Aoi-san, why are you dressed like that?”

“What do you mean ‘why’? This is who I am.”

“Even down to the rug?”

“Call it a wig!”

She slammed her coffee cup back onto the saucer with a loud clink. Ignoring the noise, I pressed on with my doubt.

“Is it for a disguise?”

“Do you think I could become Student Council President looking like this?”

“Well, probably not. But is there really any benefit to going that far just to be the president at our school?”

“What are you trying to say?”

“I just wondered if there was a reason you have to be the president, even if it means killing your true self.”

“There is.”

“And that is?”

“I don’t feel like telling you.”

Aoi leaned across the table, bringing her face close to mine and tracing my jawline with her finger.

“Or would you like to try making me say it by force?”

We were in a secluded booth, no one else around, basically a private room. In front of me was a blonde beauty emitting a mysterious aura, her low-cut neckline offering glimpses of her ample chest.

“Oh? I wonder where you’re looking?”

Noticing my gaze, she said that and retreated back to her seat.

“Is your sister doing well?”

“Thanks to you, she is in good health.”

“I see.”

She gave a simple, short reply, but I realized she had brought up my weakness—my sister—as a way of saying, “don’t ask any more than this.”

“Are things going well with your boyfriend, then?”

I brought up the topic of her boyfriend as a counterattack, but her response was a bit lonely.

“Well, this flake-out might be the end for us.”

After answering, she looked at her expensive-looking wristwatch.

“I think that’s enough. That was a good way to kill time.”

“Well then, see ya.”

With that, she stood up and left the shop. Is there actually going to be a ‘next time’? I wondered to myself, but then I muttered another outcry.

“I’m the one paying for the coffee?!”

Chapter 32: The Past Between Me and the Beautiful Silver-Haired Girl

“Hey, we finally have a chance to talk properly, don’t we?”

In a corner of a certain burger shop famous for its ‘M’ arch, the beautiful girl with silver hair and blue eyes, Michiru, pecked at some french fries while wearing her school uniform.

After Golden Week ended, when we ran into each other at school, Michiru looked at me and said, “When are you going to reminisce with me?”

My sister, who was standing next to me at the time, seemed to take a hint. After glancing between Michiru and me a few times, she said:

“Oh, I have something to do on the way home today, so you should go talk with Michiru-san, Onii-chan.”

She said it with a smile, so here I was.

Well, I say “smile,” but the corners of my sister’s mouth were twitching quite a bit…

“That was your sister earlier, right? She’s become beautiful, though she doesn’t resemble you at all.”

“Leave it alone.”

“You know, the scary vibe she gives off toward me hasn’t changed from back then to now.”

Hahahaha, so it’s been that way since back then…

“Now then, where should we start? Is there anything you want to ask me first?”

“I’ve got a lot, but for starters…”

I took a sip of coffee and asked.

“Yeah, what is it?”

Michiru followed suit, taking a sip of her orange juice.

“Michiru, what’s your last name?”

Pfft!

Just as expected, Michiru spat out her orange juice.

She hurriedly wiped the table with a paper napkin. I also wiped off the reward—no, the orange juice—that had flown onto the table and my face.

“Excuse me. D-did you not know?”

“Yeah, I thought your name was Mitsuru too.”

“I was there at the entrance ceremony, wasn’t I? My name was called when I was the freshman representative.”

“I had a bit of a shocking incident the day before the ceremony, so my memory is blank.”

“Shocking? What happened?”

Like I can tell you my sister confessed to me!

“Ah, just a little something.”

“Well, fine. Let me reintroduce myself.”

Michiru cleared her throat (ahem) and straightened her posture.

“I am Watagase Michiru. It’s been a long time, Hasemi Yuu-kun.”

My heart raced at that ear-to-ear smile, the exact same face she used to make in elementary school.

“Watagase, huh? Pretty normal.”

“Calling it normal is rude.”

“No, I just assumed it was a foreign surname. Do you have a middle name or something?”

Like Watagase Spencer Michiru? Oh, is Michiru related to a guitar or something?

“I’m a quarter, you see. My mother is half-Russian, but she’s Japanese.”

“It’s hard to call you Japanese with those looks… nothing but a sense of incongruity.”

“Can’t be helped. This is the body I was born with.”

She placed a hand on her chest, showing off her physique.

No, how should I put it… she was too detached from reality. She looked like an anime character. Combined with her pale skin, it felt like looking at the Snow Queen.

“Ah, sorry, I didn’t mean it in a bad way.”

“It’s fine, I know. I know you don’t hold any prejudice against my appearance.”

Michiru stared at me, looking nostalgic as she remembered.

“Well then, shall we talk a bit about the past? Do you remember when we first met?”

Saying that, she began to speak of that time and her feelings back then.

“Hey, won’t you let me join you guys?”

I gathered my courage and asked the kids playing soccer in the neighborhood park.

I had just moved here and didn’t have any friends. Papa and Mama were always away at work. There wasn’t a large park near my house, so I had come looking for a park where I could ride my bike and practice.

When I came to the big park alone, there were kids playing soccer, looking like they were having fun.

I had admired women’s soccer since I was little, and I used to kick around the ball Papa bought me all by myself. At my previous school, there were no girls who played soccer. Combined with my appearance, I couldn’t mix in with the boys, so I just practiced kicking alone.

After moving, seeing those kids playing soccer, I wanted to join them.

Thinking that they might not let me in if I was a girl, I cut my hair short, wore shorts, and used boys’ speech patterns.

“Hey, I want to play soccer too.”

I summoned my courage and said it.

“Ehhh? Where are you from?”
“This guy’s hair is silver! A delinquent! Scary!”
“Whoa, his eyes are blue—it’s a demon!”

“This is because my grandma is a foreigner…”

“A foreigner? Go play soccer in a foreign country!”

I was frustrated, so frustrated I felt like crying. Even though I’m Japanese just like them…

“Cut it out, you guys! Who cares if he’s a foreigner?”

That was when a boy about my age stepped in to help.

“Then you play with him!”

“Fine, I will. Let’s go, you.”
