The perverted classmates who wouldn't listen even if I asked them to stop ended up continuing the older sister act until the very end.
Even though we were the same age, this treatment.
It felt like one or two years of my age had been stolen. It was dangerous — I was starting to worry.
I might end up becoming Keiki's fraternal twin.

～Monday～
On Sunday, what was supposed to be a discussion about our worries ended up with the two of them relieving stress through their sibling role-play, and the day was spent that way.
They understood that we needed to keep our relationship hidden from Komari, but we didn't get as far as discussing what exactly we should do. No, we should have talked about holding back on the acts, but the two would never accept that. The only thing they accepted was swallowing various things from me.
Even though I had a small appetite, I was recently suffering from nutritional deficiency. But my stomach wasn't as big as Yanami-san's, so I couldn't suddenly eat huge amounts.
Lately, I had been snacking more.
"Delicious… Seaweed flavor."
"Cheese is also quite nice."
On the way to the bookstore, I tried biting into a chikuwa stick from a food truck, one from the paper cup.
It was delicious. Shikiya-san's seaweed flavor also looked tasty.
"Delicious, but heavy… Yuzuki-kun… Hold this."
With oil and seaweed flakes decorating the corners of her mouth, she gave off a cute yet somehow seductive impression. I, who could only see a woman's mouth as a lewd place, was probably seriously ill.
"Chikuwa, does it really make your stomach feel that heavy?"
"No, it's heavy to hold in my hand… My walking speed will probably slow down."
If the senior walked even slower than usual, she would look even more like a corpse.
I mustn't let her get accidentally shot by a police officer. As instructed by Keiki, I had to carry a girl's belongings.
My steps really did feel a little lighter.
Shikiya-san walked ahead, but suddenly stopped and turned to look back at me. She tilted her head.
"…Yuzuki-kun, where are you going?"
"To the bookstore… I happened to run into you on the way home from school and for some reason you followed me and we're eating chikuwa together, Shikiya-senpai."
"…Yeah… Eating chikuwa together… Cheese, give me some… Trade."
Shikiya-san, whom I had coincidentally met in front of the station, was the same as always. We traded the chikuwa stuck in the paper cups.
Really, why was I casually having after-school snacks with this person? If Ten'ai-sei saw this, it would be a bit of a troublesome situation.
I had no intention of calling out to her when I spotted her. But the moment she found me, Shikiya-san walked straight over, grabbed my hand, and followed wherever I was going.
In her mind, she was probably just happily playing with her junior as a senior. Even though her emotions were dead.
"…So, what are you buying?"
"Well, some light novels… novels I like."
"…You have money."
"Within my allowance… I'm just doing a bulk buy of about 10 books."
"…Secret part-time job is no good."
"I'm not doing one. It's just my parents' whim."
If I were in customer service, I would probably have much better communication skills. I couldn't imagine it, and I didn't want to.
But it was true that I currently had enough leeway that it might look like I had a part-time job.
In fact, I had enough in my wallet to lend money to Yanami-san without issue.
"…Hee, you won the lottery… Nice."
"It was my parents… and only a small amount."
Even a small amount was enough to make a high school student dizzy.
This morning, after receiving the dividend, both Keiki and I had been unable to keep our feet on the ground.
By the way, Keiki had also gone shopping. She said she needed some equipment and was consulting with Asagumo-san to buy a bunch of things.
Please, Asagumo-san, don't teach my little sister any weird ideas.
"Allowance… then there's no problem."
"By the way, what would happen if it was from a part-time job?"
"…There's something I want. Treat me."
"Didn't you say your family is rich?"
"Yeah, so I don't need to be treated… But I'll properly report it to student guidance later."
Terrifying. Even if my wallet got fuller from a part-time job, I must never let it show in front of Shikiya-san.
"…I'm not doing it, so relax… It's okay, I believe you."
"Haa… I'm glad you believe me. Really."
"…Are you angry?"
"If I'm teased, I might react like that."
"Sorry… But I wanted to see your reaction. Because it's cute."
"…!"
She suddenly started saying things like Yanami-san and Yakishio had been doing lately.
Why did everyone want to look down on me, a boy, and call me cute?
"…Carrying around a lot of money makes me anxious. So… Yuzuki-kun, your attitude showed it… That was a little funny and cute… I wanted to keep watching."
"I'm not happy about that… In fact, if you want to observe people, do it somewhere else."
"You're good… It has to be you."
That line was so nice it could be the title of a song.
But sadly, there were no romantic feelings attached to it.
"For now… Well, it's fine… If you're coming, walk properly. Look, we're almost there."
I urged her, but her steps were still heavy — or rather slow — and honestly dangerous to watch.
A car might mistake her for a walking corpse and crash into her. Well, knowing her, she would probably survive anyway.
"…Watch the sidewalk… Otherwise, look, I'll make you cross like that kid raising his hand."
"Komari-chan."
"…No, there's no sense of incongruity, but she's not wearing a randoseru, you know."
"It's Komari-chan… There are properly three of them. A set of girls and a boy and a girl."
"She won't split, you know. Komari is properly Homo sapiens with X chromosomes. Y chromosome… Ah, there is one!"

On the Sunday street, I spotted the young children from the Komari family. Three people waiting at the traffic light, and the small Komari holding the hands of the two little ones glanced this way.
"Ge, Yuzuki!"
"…"
"Komari-chan… Hel-lo!"
Of course, what followed next was the screams of the two young children, needless to say.
