These Dangerous Girls Placed Me Into Jeopardy

I was breathing harder from the shock. My chest was rising and falling — and Serena’s hand was still on my chest. There was no way she didn’t feel it!

“Hm...?”

Shit. She’s getting suspicious! If I open my eyes now, Serena’s bound to get so embarrassed she might actually kill me! I finally heard her call me big brother, and now I might die for it? No way!

While I was desperately trying to stay calm, repeating Please, please don’t notice I’m awake! in my head like a prayer, the pressure on my chest suddenly lifted. Then I heard the gentlest voice ever, right by my ear:

“Ah, I accidentally leaned on your chest. I’m sorry... It must’ve been uncomfortable... Want me to massage it a little?”

And then she actually started massaging my chest, her hand still resting over my heart — moving gently, with such careful, considerate motions that I could feel just how tenderly she cared for me.

...See? This is how life is. Live long enough, and you’ll experience the impossible. Ha... ha... ha...

A sister this gentle — you could only dream of something like that.

Maybe the impact was just too much. I was in a daze, and I didn’t even realize when Serena had left.

The sensation of her kiss still lingered on my cheek. And in the end, I didn’t sleep at all.

I mean, who could sleep after something like that!?

My sister! My sister actually... cough cough — she actually...!

“...Hehehe...”

I let out a dry little laugh and sat up in bed, dazed, as sunlight poured through the window.

It was terrifying. Worse than any nightmare. I really, truly didn’t expect she’d do something like that to me.

And judging by how smooth and practiced she was — and the weird sense of familiarity I had — I could only conclude: she’s done this (night visits) many times before...

W-Wait, does that mean I’m... not even a virgin anymore...!?

No, no way. It can’t have gone that far. She is my blood-related sister. Serena wouldn’t be that irrational. She wouldn’t cross that line...

But her behavior was way too intimate.

So intimate it didn’t make me happy — it scared me. Like when a complete stranger suddenly acts like they’ve loved you for years. It was overwhelming. I didn’t know how to react.

What the hell is going on?

If Serena really is a brocon, then why does she act so cold toward me the rest of the time? Is it just... a kink?

So then... was that title actually accurate?

But that “(Fake)” part... what’s the deal with that?

Feeling all kinds of complicated, I got out of bed — and immediately saw the untouched cup of coffee still sitting on my desk.

Come to think of it — why was Serena so sure I was asleep?

It was past 2 a.m. at the time. But I could’ve just been lying in bed awake. Don’t tell me... she spiked it with a sleeping drug or something...

“......”

I shook my head silently, then dumped the coffee straight into the trash can. I threw a bunch of tissues in after it to soak it up.

Yeah... now it looks like... something very different. But this was the only way to hide the fact that I didn’t drink it. 𝐟𝚛𝕖𝚎𝕨𝗲𝐛𝚗𝐨𝐯𝐞𝕝.𝐜𝗼𝗺

Let’s just forget what happened last night. Pretend nothing ever happened.

Serena probably just had too much stress bottled up. I’ll find time to talk to her properly.

Right now, what I need to do is get up, wash up, and make breakfast — just like a normal big brother.

I opened the curtains and left my room. It was still early — neither of my sisters had gotten up yet.

After washing up, I headed to the kitchen and started preparing breakfast. The ingredients were already prepped — probably by Mom before she left last night. All I had to do was cook them.

I also had to prep lunchboxes, which took a bit of time. But just two — I always eat in the cafeteria, so there’s no point in packing one for myself.

As I finished the lunchboxes and was about to /N_o_v_e_l_i_g_h_t/ start breakfast, I heard a small, shy voice behind me. So soft it would’ve been easy to miss.

“B-Big brother...? You didn’t come home last night... Where were you...?”

That sweet, hesitant tone — there was no mistaking it.

“Hm? Oh, Cora. I, uh... accidentally fell asleep in the park last night. Haha, sorry for making you worry—uh!”

I turned around with a bright smile to greet my other little sister — Cora An — but when I saw what was floating over her head, I froze on the spot.

Curled up and looking up at me, Cora’s head — tied in her usual short twin-tails — had a line of bright pink text above it. Because she was short, the letters were right at eye level...

[Scheming-Type Brocon Sister (True)]

[Cora An]

Should I say it’s as expected?

She had a name and a title too — just like Serena. The name was normal. But the title...

Not “Sweet-Type.”

Not “Gentle-Type.”

Not even “Cute-Type.”

But... “Scheming-Type”!

Scheming!?

No. No way.

Cora... my sweet, smiling sister, the one who always greeted me blushing and saying “welcome home”...

The one who made me, a total nobody, feel like I mattered... The one who looked out for me, who handed me chopsticks and poured me water...

Pffft!

Those two words — “Scheming-Type” — hit me like a spear through the heart, and mental-me spat out a mouthful of blood.

In that moment — my world completely collapsed. My whole worldview — shattered!

“......!!!”

That warm, angelic little sister I remembered... was all an act!?

No! I don’t believe it!

“B-Big brother? Are you okay? Did you not sleep well? You look pale...”

Cora stepped closer, concern on her face as she looked at my stunned expression.

But I could practically see her real expression behind that gentle smile — sneering, whispering to herself:

“Hmph. Show a guy like you the tiniest bit of kindness and he goes floating off into the clouds. What a hopeless loser. I can’t believe someone like this is my brother. Disgusting.”

M-My cute, sweet little sister... actually hates me...?

I... I wanna die...

“What are you doing?”

Serena’s cold voice snapped through the air and jolted me out of my spiral.

“N-Nothing. Just stayed up too late last night. Breakfast will be ready soon...”

“You sure you’re okay, big brother? You’re not sick, right?”

“No, no, I’m fine.”

Cora still looked worried. I forced a smile, waved her off, and turned back to cooking breakfast.

I didn’t want either of them to see how dead I looked inside.

During breakfast, I was completely zoned out. Everything that had happened since waking up in the park was just too much. My brain had fully short-circuited.

Even as I left the house, I was still in a daze.

The sister who used to be cold and distant was actually a dangerously obsessive brocon who sneaks into my bed...

The sister who used to be warm, kind, and gentle was actually a scheming manipulator full of evil thoughts...

I—I—I can’t believe in this world anymore!
