Chapter 107: The Hikikomori’s Advance

Vrr-vrr

“…”

Vrr-vrr

“…”

Vrr-vrr

“…”

It’s way too early to wake up, but I’m awake.

No matter what today holds, getting up at this hour is not what I wanted.

Today, May 6th, the last day of Golden Week.

It’s 6:30 a.m.

Why…?

“Ugh, it’s gotta be Yakko…”

Imagining her smirking face, I grabbed my phone, which had been buzzing incessantly.

Let’s see what she wants—checking the notifications—

“—!?!?”

My lock screen showed unfamiliar notifications.

They were from a social media app.

Alerts about new posts from someone I follow.

“No… no way.”

With trembling hands, I gripped the phone tightly and opened the app.

I’d completely misunderstood, thinking it was Yakko’s usual spam.

No doubt—this is from her.

Opening the app’s chat—

≪I’m hungry≫

My sister’s hunger alert hit me.

“…”

Just hungry, huh? What a letdown.

“—Oh… daily chats with my sister…”

My murmured words trembled.

A realization warmed my chest.

My sister, who’s shut out the world.

She’s reaching out about real-time, real things.

From now on, we can chat anytime, anywhere.

Casually, in real-time.

“Is she starting to open up…? Maybe she’ll show her face soon…”

This felt different from our one-sided door talks.

I’m in my room; she’s probably still locked in hers.

But… the fact we’re connected right now warmed my heart.

“…Good. This… family-like exchange…”

Just my take, but why does chatting via phone feel closer than through the door?

Physically, we’re farther apart…

“Oh!”

As I stared at the screen, touched, another message came.

≪I’m hungry≫

It was identical to the one above—and the endless string before it.

“This girl, Shiori…”

She’s really hungry, though it’s earlier than her usual breakfast time—

≪I’m hungry≫

“Whoa.”

Scrolling back, the chat was flooded with “I’m hungry.”

My dear sister is famished.

≪I’m hungry≫

More “I’m hungry” messages underscored the urgency.

“Shiori, you’re starving.”

Her desperation was a bit worrying, but hunger doesn’t care about intent.

“…Heh.”

These casual, unreserved family exchanges were somehow fun.

≪Are you seeing this?≫

≪Don’t ignore me, big brother≫

≪I’m hungry≫

“Heh. ‘Alright, alright’…”

I sent a quick reply to Shiori.

“Is there any of Yuu’s prepped food left?”

I washed my face upstairs and headed to the kitchen.

Unexpectedly starting the last day of Golden Week early, I found Yuu’s prepped food was gone, so I cooked breakfast and left it outside Shiori’s room.

“…”

Sitting on the living room sofa, staring at my phone, I realized I forgot to make my own breakfast.

“What am I doing…?”

Washing the cooking tools again felt like a hassle.

I wasn’t hungry anyway, so I skipped breakfast.

“…Oh.”

Lost in my phone, I noticed the living room clock read 9:10 a.m.

“About time.”

Assuming Shiori finished eating, I went upstairs.

The tray outside her room held empty dishes.

As usual, she ate everything.

“Thanks for eating it all.”

Having someone eat my cooking feels like they’re accepting me. It’s nice. I thanked her, took the tray, washed the dishes in the kitchen, and finished up.

This routine felt almost nostalgic lately, and I completed it with a fresh feeling, wiping my wet hands.

“…”

I must be off today.

Back in the living room, I immediately pulled out my phone.

I felt restless without it, staring at the screen.

I was really off.

Something unbelievable appeared on my phone.

I thought I’d gone crazy from the shock.

“…Huh!?”

The unbelievable thing was—

≪Big brother, I’m the one who should thank you. It was delicious≫

A new message in our chat, filled only with our words.

…And a selfie of Shiori’s hands clasped on her lap.

No face, but she’s in a different-colored version of those fluffy pajamas—so very her.

“Thank you…!?”

Her showing that cuteness, her shyness unchanged—none of that matters now.

The point is, she thanked me—

“—Shiori!!”

I was so moved, I almost cried.

She sent that thank-you right after I said “thanks” outside her room.

…She’d never thanked me for meals before.

Our one-sided door talks were only for her requests—stuff to buy.

We’ve never had “normal” or “satisfying” communication.

“Shiori… you…!”

It felt like she—and the world—was changing.

Maybe that’s a bit much…

But her reaching out, engaging with the outside world, felt like a positive sign.

My chest, my body, felt warm.

I’ve probably been living for this moment…!

“Grrr!! Let’s do this!”

I didn’t know what “this” was, but—

My Golden Week’s last day started with this inexplicable drive.

≪By the way, big brother, the meat’s seasoning was a bit better≫

“Heh. ≪Alright, alright≫… Man, this sister says the sweetest things. My cooking’s getting tastier & better thanks to my daily efforts. Gotta keep it up!”

≪But stop trying to copy Yuu-san’s seasoning. It’s unpleasant≫

“Heh. Alright—huh?”

≪And it’s subtly off. Specifically, the seasoning was too sweet. You added about 20 grams of sugar to store-bought sauce, right?≫

“You nailed it… ≪Exactly≫… Wait, wasn’t it ‘a bit better’…?”

≪You don’t need to learn weirdly≫

“…Huh? Wait, ≪What do you mean?≫”

≪That subtly bad seasoning was the charm of your cooking. Copying Yuu-san made it slightly tastier, which annoys me≫

“What…? Getting mad for improving my cooking…? ≪Did you not like it?≫”

≪Yuu-san is Yuu-san, and you’re you. Keep making bad food like before≫

“…My cooking’s nowhere near Yuu’s, sure, and maybe I’m always failing… ≪Was it that bad before?≫… Wish you’d told me sooner… Huh, weird, are my eyes sweating…?”

≪Amateurs fail when they tweak recipes. Recipes are complete, proper manuals. You’re good at studying, so why don’t you get that? My brother’s so disappointing sometimes≫

“Too harsh! You’ll make me cry! …≪I don’t get what you’re saying≫. ≪Say it clearly≫… Alright, bring it! I won’t cry!”

≪Be yourself. You don’t need to improve or belittle your cooking. I love that part of you≫

“What’s with that phrasing…? That part? Love? Sarcasm…? It’s not good, but—≪What should I do specifically?≫… Was that the right way to ask…?”

≪Don’t be influenced by Yuu-san. Your mediocre cooking is our “home’s flavor”≫

“I ain’t cooking for you anymore—oops, no, no. …If that’s what you want, Shiori, I’ll keep it as is. Tasty or not, ‘nostalgic’ is the home flavor. Got it—≪As you wish≫”

≪That’s my big brother. I love you≫

“≪Alright, alright≫… Man, you’re a smooth talker, sis.”
