While I Was Shutting in My Room for One Year, My Parent Remarried and Now I’m Living Together With Super Beautiful Stepsisters

Chapter 8: First Day of High School, Morning with My Stepsisters

The following Monday.

Last week, starting from Friday, my life with my three stepsisters began, and over the weekend, while suffering from the noise of a guitar from next door, I spent my time playing games with headphones blocking my ears.

And finally… I faced a gloomy Monday for the first time in a year.

“Aoto-kun!”

“…Huh, what?”

When I woke up in bed, a girl with large breasts was straddling my abdomen, holding a ladle… Huh?

This milk tea-colored straight brown hair… Nnn!?

“Whoa! What the hell, Momiji!?”

I slipped out and jumped up instinctively.

“It’s a morning call, you know? Normal for siblings, right?”

“Even if you do it, you wouldn’t do it while straddling like this! Normally!”

“I was actually going to wake you up with these breasts as a hot eye mask, but I stopped because it’d be too stimulating for you, Aoto-kun ♡”

Momiji deliberately pushed her large breasts together while playfully sticking out her tongue.

A big-breast eye mask, huh…

I swallowed hard.

“No, that’s not the point right now!”

“Wow, so energetic in the morning, Aoto-kun.”

“Don’t you say that!”

It’s my first day of high school… and I’m already exhausted in the morning.

“I made sure your uniform is nice and clean, okay? As your big sister.”

“You’re my little sister. But thanks.”

“I woke up earlier than anyone to prepare breakfast, too, you know? Because I’m your big sister.”

“You’re my little sister. But thanks.”

“Oh, and I washed your underwear and undershirt, Aoto-kun. Your big sister took care of it properly ♡”

“You’re my little sister… Wait, what! We agreed everyone would do their own laundry!”

“That rule’s basically nonexistent, right? I’ll wash it for you properly. I don’t mind at all. Because I’m your big sister.”

Momiji has this abnormal desire to act like an older sister.

She’s the eldest of the three sisters, so that should be enough for her… Why does she act like this even toward me, who’s older?

“Anyway, I’m going to change now, so can you leave the room, Momiji?”

“Okay, then your big sister will help you change—”

“I’m fine!”

Dodging Momiji’s overprotective onslaught, I changed into my uniform and headed to the first-floor living room.

Anzu and Yuzuna were already there eating breakfast, and I took a seat next to Yuzuna.

“Good morning, Onii-san,” said Anzu.

“Oh, good morning, Anzu.”

“Morning, Nii-san,” said Yuzuna.

“Good morning… But, Yuzuna, if you, who shares my room, had woken me up, I wouldn’t have had that morning incident with Momiji.”

“What? You got a problem with me?”

Between the guitar noise and sharing a room, I have a mountain of complaints…

But the two of them in high school uniforms feel a bit different.

Won’t their blonde and pink hair violate school rules?

“Well? Your sleeping face was… kinda cute, Nii-san.”

“Why did you go out of your way to look at my sleeping face but not wake me up?”

“Onii-san, that’s not the part to nitpick…”

“What, Anzu?”

“N-Nothing…!”

Glared at by Yuzuna, Anzu shrank like a small animal while nibbling on toast… Cute.

Wait, looking closely, Anzu’s breakfast isn’t just toast but also a huge serving of rice and a croissant.

What’s with this hotel breakfast buffet-like mix of carbs?

“Anzu, you eat quite a lot, huh?”

“Yes… I think I need to eat a lot to grow big like you two… I’ve always eaten a lot for breakfast since I was little.”

Huh, really?

On weekends, everyone’s morning schedules were all over the place, so I didn’t notice.

But… just like when we talked in Anzu’s room, she seems really conscious about being smaller in height and build compared to the other two.

Anzu already has something bigger than those two…

My eyes inadvertently drifted to Anzu’s overly large breasts, but I quickly looked away.

No, bad. I’m her brother!

“Here’s your food, Aoto-kun!”

A plate with fried eggs, miso soup, and… a massive pile of white rice was plopped in front of me.

“Thanks… Wait, what’s with this amount of rice…?”

Am I joining a powerhouse high school baseball team or something?

“You’re older than me, right, Aoto-kun? An older brother has to eat this much ♡”

Momiji said it in her usual tone, but her eyes weren’t smiling.

Could it be… she’s holding a grudge because I kicked her out this morning?

No way there’s a little sister in this world who gets mad at being called a little sister…

“Uh, Momiji?”

“Does your big sister need to reduce it? You have to ask nicely, or I won’t hand over this rice paddle.”

“Ugh…! Big sister, please reduce it.”

“Good job ♡ Well done ♡”

With not much time left, I had no choice.

It’s definitely not because Momiji’s eyes were terrifying and I had to obey.

“Ugh, Nii-san, that’s gross.”

“O-Onii-san…”

I want to crawl into a hole…

I already want to be a shut-in before even going to high school.

After getting ready in the morning, I headed to high school with my three stepsisters.

I never thought I’d actually go back to high school…

The leather shoes felt a bit small after so long, and they were unfamiliar to wear.

But the outside air after a year was slightly grassy-smelling, yet somehow nostalgic…

“Nii-san, the high school we’re going to is a bit far from here, but don’t you have any acquaintances in the second year?”

“Are you worried about me?”

“N-No, not really!”

Yuzuna denied it but pressed further, “So, what’s the deal?”

“Well, there’s none. Everyone from my middle school who applied there got into public high schools, and no one took it as their only choice, so it’s just me. I’m the only one who failed and ended up at a private school as a fallback…”

That hellish memory flashed through my mind.

If I hadn’t failed back then, I’d be living the high school dream by now…

“Ugh, Yuzuna, you made Aoto-kun depressed!”

“Huh? Why’s it my fault?”

Yuzuna and Momiji glared at each other.

“Hey, you two, don’t fight in the middle of the street—”

“Um, excuse me? Are you… Kitajima Aoto-senpai?”

Suddenly, a girl’s voice called my name from behind… Huh??
