When We Found Out We're Not Blood-Related, My Little Sister Became Seriously Love-Brained ~When a Little Sister Stops Being a Little Sister, the Ultimate Heroine Emerges!~ - Chapter 14 & 15

Chapter 14: Little Sister Wants to Be Discounted with Popcorn

Behind the food counter is a glass popcorn case with popcorn piled high. There’s only one register, so the staff looks busy.

About ten groups were already waiting, but since we came all this way, we decided to get in line too.

“It smells so good. Hey, which one should we get?”

Suzune looks happy.

Since people are right next to us, we have to lower our volume a bit when talking. So Suzune keeps getting closer and closer, and our bodies press together every time the line moves forward.

I wonder if couples in the world are like this.

How should I say it? It’s really nice.

※

When I looked at the menu board, there really was a couple discount. Moreover, the discount rate was unusually high.

The couple discount has grades, with categories from A to C based on the couple’s intimacy level. Each letter corresponds to a couple’s ABC, with A being from just starting to date up to kissing.

And at C, the discount rate is an incredible 80%. A 2,000 yen couple set (large popcorn and two drinks) becomes 400 yen.

It’s an over-the-top campaign, but apparently it’s for a limited time, so it’s quite generous. The other couples are choosing their menus happily while playfully bantering.

(Strictly speaking, we’re not even at A, but they wouldn’t actually check, right?)

“Hey, are these photos of people who ordered the couple set?”

Suzune pointed at the cork board in front of the store.

Dozens of couple photos are pinned to the board.

“Everyone’s holding popcorn, so I guess so?”

“Wow. I wonder if there’s anyone we know?”

Suzune is looking intently at the photos.

Suzune is somehow excited.

This side of her is age-appropriate.

※

I also peered at the cork board.

“There’s no way there’d be anyone we know… wait, huh?!”

As I traced with my finger, it stopped at a face I recognized.

“Huh?”

Suzune was surprised and looked at where my finger pointed.

“Isn’t this Saitou?!”

“It really is! He’s in a photo with a beautiful older woman!! Isn’t that his real older sister?”

Suzune grabbed both my hands and bounced up and down.

“No, he shouldn’t have an older sister.”

“Then isn’t it his girlfriend?”

The woman in the photo was a beauty in her early twenties with a calm atmosphere. Maybe a college student?

Age-wise, it’s not impossible. But wait, this is Saitou who’s been designated as industrial waste by the girls in our class, you know?

…That’s normally not possible.

But wait.

If I say that, I’m with Suzune, so I’m similar.

“I’ll ask him when we go to school Monday.”

“Tell me too! Hmm, that Saitou-kun huh.”

Suzune is kind even to Saitou.

She probably doesn’t judge people much by appearance.

Well, until recently, she was harsh with me though.

Maybe it’s because I’m with Suzune now.

Even trivial things feel fun.

“Hm?”

Suzune looked at me questioningly.

“No, I was thinking it’s fun being with you.”

Suzune clasped her hands together around her belly button area.

She’s swaying her body embarrassedly.

“When we’re together, fun things keep increasing!”

I thought that was exactly right.

Next to the cork board was an explanation saying that the best couple of the day gets a commemorative gift and has their photo taken.

※

Our turn came.

“Welcome. For couples, we recommend the limited-time couple discount. Which will you choose?”

The staff asked for our order.

(What should I do? But that means we look like a couple, right? That’s kind of nice. It’s staff-approved, so maybe A would work?)

“Th-then A…”

Just as I was about to say it, Suzune interrupted.

“C please!!”

What is this person?

She’s a total liar.

C is for couples who’ve progressed to sex, you know? In other words, it’s the supreme option permitted only to couples in their final form.

“H-hey. Don’t lie.”

I said in a low voice.

“Huh? We’re siblings who’ve been together for almost 17 years, you know? We’ve long since surpassed some couple’s C.”

(No, we haven’t surpassed even A, let alone C.)

“What if they ask for proof?”

When I said that in her ear, Suzune answered calmly.

“There’s no way they’d ask. We can’t have sex here.”

Suzune’s voice is gradually getting louder.

The staff apparently heard too.

“Then, may I confirm?”

The staff said that while looking at our faces alternately.

(See, because Suzune said something unnecessary.)

“But here means…”

The staff answered my question with a smile.

“Yes. So, on the back of your hand… is fine?”

※

Smooch.

Suddenly my chin was pulled sideways and something soft was pressed against my lips. But when I turned around, Suzune’s face had already moved away.

(Huh? The staff wasn’t finished talking yet… Plus, I couldn’t hear it well.)

However, Suzune has a face like nothing happened.

I just now.

Got kissed on the mouth, right?

This person, even though the staff was still saying something about the back of the hand, jumped the gun and kissed me, right?

As I covered my lips like a maiden, for some reason voices saying “Ohhh” arose from around us, and scattered applause broke out.

“Being able to date a girl like that is seriously enviable.”

I heard such a voice from a group of guys a few groups behind.

(That’s right, that’s right. My Suzune is cute.)

…No, that’s not it!!

You shouldn’t sell yourself cheap for a discount!

※

When I turned my gaze back, the staff was also smiling wryly.

“Sorry about that. This is on the house. And today’s best couple is you two!!”

The staff said that, took our photo, and gave us a commemorative envelope and chicken combo.

As a bonus we also got fried chicken and fries, becoming quite a dinner-sized amount. We decided to head to the theater with our food-loaded tray.

“We got lucky. We got all this. They gave us movie tickets too, so let’s come again together ♡”

Suzune is in a great mood.

By the way, the movie tickets are the best couple commemorative gift.

However, I wasn’t in a position to care about that.

“H-hey. You kissed me earlier, right?”

Then Suzune tilted her head.

“Who knows? Isn’t it just your imagination? Oh, by the way, the old man next to you was moving his trembling lips?”

Hey hey. This person.

What a terrifying thing to say.

“So you’re saying that old dude was my first kiss partner?”

Suzune covered her mouth.

“Oh. So it was really Yuuma’s first time. Then even if Yuuma kisses someone next, it won’t be a first kiss anymore. Hehe…”

Somehow, Suzune looks really happy.

“So it was you, Suzune, right?”

No, I obviously know it was Suzune. But it’s a memorial moment, so I want to confirm properly.

“Who knows. Did you know? A kiss doesn’t count if it’s under 0.5 seconds?”

“What kind of rule is that? I’m hearing it for the first time in my life.”

Then Suzune stopped. Her voice is small too, and she’s looking down a bit, somehow seeming anxious.

“…Because I’d hate it if someone else took it.”

“Huh?”

“When I was attacked at the park before, I was scared, but I thought that if I’d been kissed or something, my first would have been with someone other than Yuuma, and I got really scared afterward. So I’m giving it now…”

“Won’t you regret it?”

“There’s no way I’d regret it. Rather, I’m happy… I mean, for things like this, who you do it with is more important than what you did!!”

When she says it so confidently, it’s strange how it starts to seem correct.

※

“But you know…”

Suzune continued speaking.

“Hm?”

“It was too quick, I didn’t feel anything…”

Suzune said that while touching her lips.

“Ahaha. True.”

Same for me. I barely remember anything.

Then.

Smooch.

This time I was kissed on the cheek.

“So next time, I want Yuuma to properly kiss me.”

Suzune is looking straight at my face.

“Y-yeah… I’ll do my best…”

“It’s fine when Yuuma’s feelings are decided. But if it’s too late…”

“Too late?”

I’ve seen this kind of scene many times in dramas. At times like this, what the heroine says is usually decided.

“If it’s too late, I’ll find someone else good.”

Everyone says something like that.

Even if it’s a joke.

I don’t want to hear such words from Suzune’s mouth.

Then Suzune continued speaking.

“If it’s too late, I’ll make you eat sake bonbons and before you know it, we’ll have a baby!!”

Huh? This person.

What is she saying?

Her thinking is like an old man’s.

Does she mean I’ll forcefully push her down with alcohol’s power?

There’s no way I’d do that to precious Suzune.

“So who’s the one being fed?”

When I asked, Suzune answered.

“I’ll feed them to you. Obviously.”

“So there’s no chance you’ll go to someone else because you can’t wait?”

Suzune turned both hands outward and answered as if it were obvious.

“Huh? Are you stupid? I can’t do it with anyone but the person I like. There’s no way that would happen. I’ve finally become able to honestly convey my feelings to you. It’s still nowhere near enough.”

Suzune-san appears to be angry.

My little sister is cute and just a bit hateful.

Chapter 15: A Handkerchief Is Essential for Movies with Little Sister

The movie will be shown in Theater 10.

“Where’s E11? Found it. This seat.”

I prompted Suzune to sit next to me.

I need to turn off my phone.

As I picked up my phone, I heard Suzune’s voice.

“Ahh.”

When I looked at the seat next to me, Suzune was opening her mouth.

“What? Are you sleepy?”

When I said that, Suzune gave me half-lidded eyes.

“Obviously I want you to feed me with ‘ahh.’ Don’t be mean.”

Oh, is that it?

I genuinely didn’t understand.

“Here, ahh.”

I grabbed a french fry.

(That’s right, I’ll return the favor from before.)

I pretended to kiss the fry, then tossed it into Suzune’s mouth.

Then Suzune’s cheeks turned bright red.

“A-an indirect kiss. You pervert! I’m only a little bit happy about this!!”

Hey hey, what kind of tsundere girl is this?

Plus she’s subtly honest.

Also, you kissed the fried chicken in the bento before too.

…This person is pumped up even before the screening.

“Oh, did I surprise you? It was just pretend. Don’t worry.”

When I said that, Suzune puffed up her cheeks.

“Huh? What’s that, that’s fraud. Give back my racing heart.”

“Your heart was racing?”

“So much. I mean, it’s always racing when we meet. It’s racing now too. Hey hey, more importantly, properly kiss it before feeding me.”

Suzune is using a very spoiled voice.

“Alright alright. You’re in a good mood though.”

“Because I’m happy about the movie theater date, nyan.”

Suzune imitated a cat paw with her right hand.

“A movie theater for a date is pretty normal, isn’t it?”

“That’s not true. It’s my first time.”

“…Huh?”

※

Then the theater went dark.

“Oh, it might start soon.”

When I said that, Suzune opened her mouth again.

“The fries?”

Suzune is clasping both hands together in front of her chest.

“Mm. It’s bad manners, so maybe later.”

“…Bully.”

When she pursed her lips, Suzune sulked.

She won’t make eye contact with me, but her sulking profile is also nice.

Now, the movie.

※

The movie had content combining romance and time-leaps. I think the setting where the protagonist and heroine swap bodies in dreams across several years is innovative.

It’s a Friday night showing, so it’s almost full. Looking at the surrounding seats, surprisingly the audience was all ages and genders. The heroine is set as countryside-raised, so it’s probably accessible to a wide range.

When I looked at Suzune’s profile, she was really concentrating on the movie. I was a bit worried since it was anime, but she seems to like it.

Near the climax, the protagonist and heroine keep missing each other and can’t kiss, then the heroine gets caught in a disaster. From here the story will probably develop rapidly.

Suzune grabbed my hand.

The force got stronger and stronger.

“Uuu.”

Suzune started crying.

Everyone’s attention gathered at once.

(Other customers, sorry!!)

“Wait a sec, excuse me.”

I covered Suzune’s mouth.

She managed to stop crying, but for the remaining 20 minutes until the end, I was so worried she’d cry again that I couldn’t relax at all.

In the final scene, the protagonist and heroine reunited, kissed, and it ended.

(Somehow Suzune has her eyes closed making a kissing face.)

When the main feature ended, several people stood up. I’m the type who wants to watch until the ending credits…

What about Suzune?

“Uuu…”

When I looked at Suzune, she was crying again, and I broke out in a cold sweat again.

But I don’t feel cold stares.

When I looked around, other audience members were crying too.

(This time… safe!!)

※

“I feel purified.”

I hear such conversations around me.

When the movie’s ending credits finished and the theater brightened, Suzune’s eyes were bright red.

“Let’s go?”

When I held out my hand, Suzune grabbed it.

(Damn, my back feels gross from cold sweat.)

“Somehow, I feel really purified. Hey, thanks for choosing something interesting!!”

Suzune is in a good mood.

Honestly, I was on edge and far from purified. But I’m glad Suzune is satisfied.

As we walked, Suzune came around in front and looked at me.

“Weren’t you moved, Yuuma?”

“No, I wasn’t in a position to be.”

Then Suzune grinned.

“Hmm. Yuuma, you’re cold!”

Uww.

It’s because of you though.

This brat!!

※

When we came out of the theater and were throwing away the popcorn and other trash, I noticed we were gathering looks from around us.

The cause is undoubtedly the beautiful girl with bright red eyes next to me.

I hear voices here and there saying “Making such a cute girl cry, how terrible.” Everyone seems to have been purified by the movie and become angel-like with kind hearts.

Still, was Suzune always such a crybaby?

We left the movie theater and stopped at a nearby cafe.

We sat side by side in the tall chairs at the counter seats.

“The movie was interesting, wasn’t it?”

After a movie theater date comes the review session.

“Yeah, it was really good. Especially the last scene. I’m glad they could properly reunite and kiss.”

Suzune looks happy. Surprisingly she seems to be the type who gets emotionally invested.

“Do you long for that kind of love?”

Then Suzune touched her sidelocks and fidgeted a bit.

“We’re romantic too.”

“Why?”

Honestly, I don’t know where such an element exists.

“Because. I thought we were siblings and had given up on liking you for so long. Then I found out we’re step-siblings and could properly convey my feelings.”

True, it’s similar to separation and reunion.

“You’re right.”

So that’s why Suzune cried so much at the movie.

I finally understand.

Suzune made a slightly apologetic face.

“You know. Sorry for saying I like you all the time every day. But I want to tell you a lot. For all the times I held back.”

“No no. I’m sorry too.”

I feel bad about myself for not being clear. The kiss earlier was like that too.

Suzune grabbed my hand.

Under the table, we layered our hands with fingers interlaced.

“It’s okay. I understand. That Yuuma thinks about me. Even if we’re not blood-related, there’s still Papa and Mama and various things, right?”

“…Don’t you get anxious?”

“No no. It’s okay. With the chocolate, I understood that Yuuma thinks of me as a girl.”

Suzune looked down embarrassedly.

It’s roundabout, but she’s probably talking about how I got aroused by Suzune.

(As I thought, this person remembers what happened then.)

Should I ask boldly?

“Do you dislike being lusted after?”

“Lu-lust… There’s no way. I’m happy to have the person I like feel that way.”

(That makes her happy too? That makes my heart race.)

“Should we head back soon?”

When we left the store, Suzune pulled my hand.

Apparently she wants to go back toward the movie theater again.

“This way. I haven’t decided yet.”

Suzune said while pulling my hand.

“Haven’t decided what?”

“I haven’t decided what to watch next time we come.”

Suzune said that and pursed her lips.

I see.

Suzune wants to come to the movie theater again.

When I picked up several preview flyers, Suzune snuggled her body close.

“Yuuma. I wonder if you’ve been to movies with other girls. I don’t like that.”

A monologue? That’s not like Suzune.

“Suzune. Could it be your inner voice is leaking?”

Then Suzune made a surprised face and covered her mouth with her hand.

“This was my first time coming to a movie with a boy.”

“It’s my first time too. If you’re curious, just ask.”

When I said that, Suzune’s voice got quiet.

“Because I don’t want you to think I’m annoying.”

“There’s no way I’d dislike you for that.”

I patted Suzune’s head.

Then Suzune rubbed her cheek against my patting hand.

“Ehehe. You’re kind, like an older brother. I want you to only watch movies with me.”

(I actually am your brother though!!)

“I’ll only go with you, Suzune.”

Then Suzune closed her eyes happily.

“Hey. Pat me one more time.”

(Being outside like this, it’s like we’ve become normal lovers, not step-siblings at all. I want to be together a bit longer.)

※

Oh, come to think of it…

“Suzune. There’s apparently a festival pre-event happening near our neighborhood, want to stop by on the way home?”

“Yeah. Let’s go!!”

Suzune opened her eyes wide and smiled like a sunflower.
