[Volume 1 Chapter 1] When I confessed to the girl I liked, her twin sister came along as a bonus

Chapter 1: The Confession to the Older Twin Seems to Have Succeeded

“I’ve got a twin sister, you know.”

“Huh?”

For a moment, I thought I misheard.

That’s how unexpected her—Yukizuki Tsubasa’s—words were.

Her long, brown-dyed hair is adorned with a bat-shaped hairpin on the left and matching earrings.

It’s summer, but she’s wearing a long-sleeved blouse with the sleeves rolled up, a refined wristwatch on her left wrist.

Not for sun protection—she just prefers long sleeves rolled up as her style.

Her checkered skirt is quite short, boldly showing off her pale thighs.

Her chic hairstyle and outfit suit her perfectly, complementing her refined, elegant features.

Yukizuki is known as one of the top beauties in school.

Rumor has it she used to be a reader model.

Apparently, she gained popularity quickly but retired after just six months—

Her sudden, mysterious exit caused quite a stir among the girls.

Yukizuki herself brushed it off with a casual “I got bored,” unfazed by the commotion.

Always carefree and laid-back, Yukizuki has a knack for stirring things up.

One early summer day—I found myself alone with her in the classroom after school.

I’d finished taking out the trash for cleaning duty and returned to find Yukizuki by the window, messing with her phone.

Yukizuki sits at the top of the so-called school caste.

She’s not just tight with her fellow gals but has also won over top students and athletic aces, leading them all.

Reigning at the top, she’s friendly with everyone, never looking down on anyone.

At the peak of the caste, yet completely indifferent to it.

For example, she insists even a classmate like me, with barely any connection, call her “Yukizuki” by name.

She once laughed that being called by her surname makes her itch.

With that attitude, even at the top, she rarely faces jealousy or resentment.

Seeing her alone in school, without her usual entourage, is rare.

“Yo, Masaki!”

“Ah, yeah.”

Being called out by her threw me—Masaki—off a bit.

“Taking out the trash again? You always volunteer for that during cleaning duty. Just decide it with rock-paper-scissors or something.”

“Well, whoever notices it should just do it.”

I set the trash can in the corner, grabbed my bag, and turned to Yukizuki.

“I like you,” I said.

I didn’t think it through; the words just slipped out.

The rare chance to be alone with Yukizuki was the biggest reason—

But in my head, a voice screamed, “Now’s the time.”

I didn’t question it, and before I knew it, the words were out.

Honestly, I hadn’t even considered confessing until the moment the words left my mouth.

But you can’t take back what’s said.

Running away and pretending it didn’t happen goes against my principles.

Manliness—

It’s an outdated, almost fossilized concept, but it’s important to me.

I wasn’t taught it; it’s just something I picked up naturally by my second year of high school.

Don’t sweat the small stuff, face challenges head-on, and live boldly—that’s my creed.

Sure, dragging out my confession this long wasn’t exactly manly, but I’m still a teenage high schooler, so cut me some slack.

Anyway, I said it.

I’ll accept the outcome like a man. Even if I know I’m headed for rejection.

“…”

Yukizuki stopped fiddling with her phone, her large eyes blinking rapidly.

Then she stepped close, looking up at me with an upward gaze.

Her blouse buttons were undone, revealing a glimpse of her cleavage.

Even the edge of her black bra peeked out.

Bold and sexy, just like Yukizuki.

Normally, I’d be flustered and look away.

But right now, I had to meet her eyes.

To show her I was serious.

Yukizuki stayed silent for a good thirty seconds—

And then came her line about having a twin sister.

As a response to a confession, it was way too creative.

“…Did you hear what I said?”

“I heard you.”

“…”

I didn’t ask about her family.

A twin sister is news to me, but… couldn’t she pick a different topic to dodge with?

Being alone with Yukizuki, who’s always surrounded by friends, is a once-in-a-blue-moon chance.

No, it might not come again until graduation.

It’s the summer of our second year.

More than half of high school is left, but I can’t expect multiple chances to confess.

That’s why I mustered the courage, trying to play it cool—

But I never imagined I’d get such a baffling response.

“Whoops, my bad, my bad. That’s a weird response, huh? I wasn’t trying to be funny.”

“N-no, I’m the one who sprang this on you. You don’t have to answer right away—”

“I did answer. I just left out a few words.”

“…?”

No matter what words you add to that, it’s not a response to a confession…

“I don’t tell many friends about my twin sister.”

“Oh, really?”

Now that I think about it, it’s odd.

Yukizuki is the queen of the school caste.

Even a guy like me, with a tiny social circle, hears rumors.

A juicy tidbit like the stunning Yukizuki having a twin sister should’ve spread through the school like wildfire.

If no one knows—

“Is your sister not at our school?”

“Bingo. She goes to Shuka Girls’ Academy.”

“Shuka…”

It’s a prestigious all-girls school, middle and high school combined, on the same train line as ours.

Rumor has it it’s full of refined young ladies, and their pristine white sailor uniforms are the envy of many girls.

I see their students on the train often.

Not all of them get chauffeured, despite the “rich girl” reputation.

It’s close to our school, so it’s not surprising that siblings of our students might attend.

“Don’t tell me… you need your sister’s permission to answer my confession?”

“Not quite, but you’re kinda close.”

Yukizuki slips her phone into her skirt pocket.

“My sister’s name is Fuuka.”

“Fuuka…”

“Yup. Masaki, if you’re willing to two-time with me and Fuuka, I’ll go out with you.”

“…!?”

Again, it took a moment to process what she said.

Go out with her and her twin sister…?

“Yukizuki, what kind of joke—”

“…”

I started to ask, but Yukizuki’s face was deadly serious, a look I’d never seen before.

If she can fake that kind of sincerity, she should be an actress.

A twin sister was shocking enough, but dating both her and her sister?

As a confession response, it’s beyond creative…

“…Sorry about that!”

“Huh?”

“That was weird, right?! I mean, it was a joke!”

“What… a joke?”

“Haha, the twin sister thing was a lie! Did I shock you? You were so serious, I couldn’t help teasing you. Sorry, sorry.”

Yukizuki clasps her hands together, bowing apologetically.

“Don’t take it so seriously! Alright, I’m heading out. Really, sorry—”

“Wait.”

I grab Yukizuki’s wrist as she tries to slip past.

“M-Masaki?”

“I said I like you, Yukizuki.”

“Y-Yes?”

“We’re not even friends… but I’ve watched you for a while. You’re cute, and I like your style.”

“W-Wait, Masaki?”

“I’m not denying that, but it’s not just your looks. I know you’re not the type to tease someone who confesses to you.”

That’s right. Yukizuki is friendly and kind to everyone.

Of course, she has sides she doesn’t show to a mere classmate like me.

But I’m certain she wouldn’t mock a serious confession.

“If you say you have a twin sister, I believe it. And if you say I can date you by two-timing with her, you’re serious, right?”

“…No way. What do you even know about me, Masaki?”

“Not much. But I know myself. I wouldn’t fall for a girl who’d mess with a guy’s confession. No way.”

“…”

I hold her wrist, and she doesn’t pull away.

That confirms it. Her response is her true feelings.

No, her attempt to brush it off was too clumsy.

Even a dense high school guy like me can’t be fooled by that.

Now, what to do?

Her response was beyond unexpected, but it’s her honest answer.

So, how should I reply?

I confessed, and she answered sincerely. I can’t be vague now.

What to do?

What to do?

No, the answer is obvious.

If Yukizuki’s words are true, there’s no other choice.

“If that’s what the Tsubasa Yukizuki I like says—then I’ll date both of you.”

“Eh!?”

You’re surprised, Yukizuki, even though you brought it up?

Well, my response might just match hers in boldness.

“I’m like you, Yukizuki. I don’t lie or joke about something this important. I want to date you. If there’s something I need to do for that—I’ll do anything.”

“Anything…? Are you serious?”

Yukizuki sizes me up with a piercing gaze.

It sends a shiver down my spine.

It’s a look of intelligence and resolve, unlike the carefree smile she shows in class.

Another side of her I’ve never seen.

“Yeah, even if it means a threesome with you and your sister, I’ll make it work!”

“I didn’t say go that far!”

Looks like I jumped the gun a bit—okay, a lot.

But a man who commits must charge forward, no matter what.

“…I’m not saying it’s off the table, though.”

“You’re not!?”

Maybe I’m not the only one riding this momentum.

My reckless confession has veered off course—quite a bit—but it’s charging full speed ahead.

And I have no intention of stopping.
