Dumped by One, Chased by Another? My Ex's Sister Is a Gal and She's Coming for Me - Episode 4

What do I do, what do I do, what do I do?

He saw us. He saw us. He saw us.

Kengorou—my boyfriend since high school.

He saw me with Senpai.

He saw us together.

And now he’s running away.

Watching his back as he disappeared, I was overwhelmed with crushing regret.

________________________________________

“Onii-san!”

And then—someone else saw us too.

________________________________________

“Onee-chan, what is going on?”

“W–wait, Haruki, this isn’t what it looks like—”

“What were you doing? Explain it properly.”

“O–okay, I will.”

________________________________________

Haruki has always been smarter and more mature than me.

Even now, she’s calm, not showing the slightest emotion.

It’s terrifying.

I don’t know what to say.

But I have to say something.

I have to.

________________________________________

“Senpai was just… giving me some advice, that’s all.”

“Advice? In a love hotel? What kind of advice?”

“Th-that’s… well…”

________________________________________

Haruki narrowed her eyes and sighed.

I instinctively looked away—toward Senpai, standing beside me.

He, of course, looked perfectly composed, as if nothing at all was wrong.

________________________________________

“Haruki-chan, right? You’re still in middle school?”

“I’m in high school.”

“Ah, I see. Well, you might not understand this yet since you’re still a kid, but relationships are complicated. Just because you’re dating someone doesn’t mean you’ll stay together forever. Feelings can change, you know?”

________________________________________

Senpai spoke in a calm, condescending tone, like an adult explaining something to a child.
________________________________________
“…So, what you’re saying is, Onee-chan is breaking up with Onii-san? That’s what I gathered from what you just said.”

“…Yeah. That’s right.”

________________________________________

The words caught in my throat, but I forced them out.

Because really, what else could I do?

There’s no other choice.

I have to choose one of them.

Even if it’s all happening so suddenly.

I’ve been torn up about this for a long time. I’ve been confused, unsure.

Haruki stares at me with those unreadable eyes.

Since she started high school, she barely shows emotion in front of me anymore.

I don’t know why.

I chalked it up to a phase, a kind of adolescent rebellion. I never thought much of it.

Maybe she was just too mature for her age, I told myself.

But right now… that blank expression of hers is terrifying.

________________________________________

“Hmph. Fine. Do whatever you want.”

________________________________________

She said it without even a flicker of emotion.

________________________________________

“I’ll do whatever I want, too.”

________________________________________

I didn’t fully understand what she meant by that whispered remark.

But at the very least, she didn’t seem like she was going to confront or accuse me.

Thank goodness.

If that’s the case, then maybe everything will be okay.

________________________________________

“Well then, how about the three of us grab a meal? My treat.”

________________________________________

Senpai flashed a dazzling smile.

I know she’s just my sister, but I can’t help feeling a little uneasy.

I want him to smile like that only when he’s with me.

Still… he’s so handsome.
________________________________________

“No thanks. I have plans.”

“Plans?”

________________________________________

She’s not in any clubs, and I’m pretty sure she doesn’t go to cram school either.

So, what could she possibly be doing?

________________________________________

“I have to go to the hair salon.”

“The… hair salon?”

________________________________________

Going to the salon—I can understand that.

But saying she has to go makes it sound urgent, almost strange.

What did she mean by that?

________________________________________

“Hah, what a shame. Next time, then.”

“Sure. If there is a next time.”

________________________________________

Haruki was cold toward Senpai, downright frosty.

Without sparing either of us another glance, she turned and walked away.

________________________________________

“Stylish girl, though,” Senpai said.

“Stylish?”

“Well, yeah. She said she’s going to the salon, right? Pretty sure she just got a haircut not long ago. Maybe she’s going for a full makeover?”

“…You really shouldn’t be eyeing other girls, you know?”

“C’mon, I would never. You’re the only one for me.”

________________________________________

He said that as he pulled me into his muscular arms.

My heart skipped.

Just remembering the pleasure he’s given me made my body heat up and ache with longing.

Pressed together like that, we started to walk.

My mind was already completely consumed by thoughts of Senpai.

“I won’t forgive you.”

________________________________________

I pressed the button to stop the recording app on my phone.

________________________________________

“You betrayed Onii-san. He loved you so much.”

________________________________________

I clenched my phone so tightly I thought it might break.

________________________________________

“I’ll never forgive you, Onee-chan.”

Muttering a curse against the only sister I have, I began laying out my next move.
