I, Who Longs To Be A Dependent, Have Decided To Be Owned By A Yandere - Chapter 51

Side Story: Professional Sister’s Style

“I want to eat my meals with onii-chan’s cells as a side dish~”

On a Sunday morning, the younger sister, Kiriyama Sumire, wakes up early.

At the crack of dawn, around 4 a.m., she awakens in the futon of her brother, Kiriyama Akira, her eyes sparkling brilliantly.

“By monitoring onii-chan’s brainwaves while he’s asleep, I found that his deepest sleep occurs around 4:12 a.m.”

Even though it’s only just beginning to dawn, she’s already fully awake.

“At this time, no matter what I do, he won’t wake up.”

With that, she starts to burrow her head into her brother’s clothes.

“There are some people who make morning radio exercises a daily routine, right?”

While repeatedly sticking her head into her brother’s clothes, her face is marked with seriousness, occasionally showing glimpses of her pride as a professional little sister.

“It’s the same for me. This is my daily routine. This precious time when I can enjoy everything from onii-chan’s abdominal muscles to his intercostal muscles, I don’t want to waste any movement.”

Sumire’s actions show no compromise. There lies her commitment as a professional little sister.

“I won’t touch the nipples. It would wake onii-chan up… I aim strictly for the abdominal muscles to the intercostal muscles, as quickly and rhythmically as possible.”

At 6 a.m., when it’s most likely that he would wake up, Sumire leaves his futon and returns to her own room.

Would it be okay to leave her beloved onii-chan?

“Onii-chan doesn’t approve of anyone entering his room without permission.”

Returning once again to her onii-chan’s bedroom, Sumire uses a sticky carpet cleaner and masking tape to perfectly erase any trace of her presence, such as strands of her hair.

“I need to erase the fact that I was in this room before he wakes up. While I’m at it, I subtly plant “my erotic images” on the desktop screen of the laptop onii-chan uses to produce a subliminal effect. By changing it every day, I prevent him from getting bored and guide him to develop a sexual consciousness towards me.”

Sumire, who returns to her room to fetch her tools, tirelessly locks her brother’s room.

“It’s hard work, but when it comes to onii-chan, the happiness far outweighs the effort.”

A smile appears on Sumire’s face.

“It’s all for the sake of a happy life with onii-chan, so I’ve never found it difficult.”

At 7:30 a.m., Kiriyama Akira wakes up. But Sumire doesn’t leave her room.

“Onii-chan isn’t really a morning person. It’s essential to make the first contact, but if I act hastily, I might upset onii-chan and lower his favorability towards me.”

She closes her eyes and meditates, showing no signs of impatience.

“In about thirteen minutes and thirty-two seconds, I’ll pretend as if I’ve just woken up due to chance and greet onii-chan good morning.”

With her perfect time management, Sumire, who had been focusing on the second hand, moves.

“Onii-chan, good morning! I love you!! Let’s get married!!”

“Good morning, no way.”

Despite his dismissive response and suspicious look towards the camera, Sumire unabashedly clings to his arm.

“You’re not wearing a bra, are you?”

“Eh, you noticed? Onii-chan, you’re so lewd!”

“…And what’s with this video camera?”

Watching her brother, coffee in hand, return to the second floor, Sumire is brimming with energy, seemingly unaffected by the unfair treatment she just received.

“Well, onii-chan’s reaction is just as expected. Rather, I’m happy that he’s reacting at all.

Whenever I have a chance to physically contact onii-chan, I take off my bra as much as possible. I do this even in winter. The first step is to make him think, “This little sister is okay to attack.”

Looking delighted, she talks about the tricks of inc*st with utmost seriousness.

“It’s also important to make him conscious of marriage. It’s like Pavlov’s dog…in other words, a conditioned reflex. When I say “marriage,” I press my chest against him, conditioning him to associate marriage with sexual consciousness. By doing this, the moment onii-chan lays a hand on me, he’ll only be able to think about “marriage.”

As a professional sister, she wants to do everything she can. That’s what Sumire says, her eyes fixed solely on her brother’s back.

At 11:30 a.m., Sumire begins preparing lunch for her brother.

“On holidays, the only one in our house who doesn’t have a proper breakfast is onii-chan. He just has coffee and toast. Since mom is in charge of dinner, lunch is a great opportunity for me to step in.”

What Sumire starts making is omelette rice and salad. It looks like a normal lunch, but here is where her skills as a professional little sister shine.

“I add ingredients that boost vitality. “Natto” in the omelette rice, “broccoli” in the salad, and so on. For onii-chan’s sake, I don’t want to use any drugs, so I’m betting everything on the ingredients.”

While cooking skillfully, Sumire speaks only to the camera.

“When I first met onii-chan, I couldn’t cook at all. In fact, I was bad at it. But when onii-chan made omelette rice for me when I was hungry, I thought, ‘I want to make omelette rice for this person and this person alone.'”

Even though she’s a professional sister, Sumire is just a girl in love. The staff saw a human side to her as she blushed while cooking.

After going back and forth on whether to play the “ah~n” game while clinging to her brother from the front, Sumire starts setting up a game console in front of the living room TV.

“One of onii-chan’s few hobbies is “gaming.” Playing games together on Sundays is becoming more and more of a daily routine.”

After setting up the game console, she suddenly starts taking a shower. What on earth is going on?

“You’ll see.”

The professional little sister whispers mischievously to the camera.

“Onii-chan!! Let’s play games~!!”

The Sumire who went to call Akira looks nothing more than an innocent little sister. This level of excitement is not an act, it’s genuine…that’s why it resonates with Akira, her brother. She told the camera so.

“Eh, you’re still filming? What is this, a close-up interview with Sumire?”

“Onii-chan, here, the controller.”

“Yeah. But don’t just sit on my lap like it’s the most natural thing in the world…huh? You took a shower?”

“Yeah! Just now!”

“You should at least dry your hair properly…you’re like a puppy that’s been picked up by a delinquent after being caught in the rain…can’t be helped, I guess…”

When Akira gets up to go to the bathroom to get a towel, Sumire grins as if everything is going as planned.

“He’ll dry my hair for me. Yes, this is one of my goals, but not the only one.”

Sumire, wearing Akira’s oversized shirt, pulls at her neckline as if to show off to the camera.

“It’s onii-chan’s shirt. It doesn’t fit and since I’m not wearing a bra, he’ll see everything if he looks down even a little. Plus, since I just washed my hair, it smells like onii-chan’s favorite shampoo.”

The professional little sister, like a seasoned hunter, closes her eyes and nods deeply.

“Today, I’ll definitely make him fall for me.”

During the game, Sumire clings to her brother from the front and makes a strong appeal…but her beloved brother doesn’t attack her.

“Any ordinary brother would have fallen by now.”

After finishing the game with her brother, she speaks with conviction to the camera.

“But my opponent is my onii-chan, Kiriyama Akira. Even though I was sitting on his lap the entire time, he never once looked down. He was really pissed off at the game. He was saying things like, “I’m gonna file a complaint, you idiot!!” and making prank calls.”

Despite her obvious failure, Sumire shows no signs of being disheartened.

“Yes, I’ll learn from my failure and next time, I’ll take off my panties. I have no intention of giving up. The person I love most in the world is onii-chan, and I’ve never even considered another man as a man.”

Sumire declares confidently.

“I will definitely be happy with onii-chan.”

This strong statement hints at her unwavering resolve to marry none other than Akira.

At 8:30 p.m., with Akira’s bath time approaching after dinner, Sumire faces the bath temperature control panel with a serious expression.

“I adjust the bath temperature according to onii-chan’s physical condition. But generally, it’s lukewarm. The longer he bathes, the more “stock” he produces… I enter the bath right after that.”

She shows her biggest smile of the day to the filming crew.

“It’s the happiest time of my life. Being enveloped by onii-chan, it’s the best time to think only of onii-chan. It’s a privilege of a little sister.”

While preparing an empty two-liter plastic bottle, Sumire seems to be eagerly awaiting her turn.

Having told us that all that was left was to sneak into her brother’s futon late at night, we, the camera crew, posed our final question to the well-mannered Sumire.

――What is a little sister?

“For a brother, she is the best woman. The best partner. Someone who understands him better than anyone else, someone who can love him more than anyone else.”

Listening to the sounds of his life through a bug planted in her brother’s room, she, who talked about waiting for him to fall asleep, was facing her brother with seriousness until the end.

“That’s what a little sister is, isn’t it? At least, to me, that’s what being a little sister is, and nothing else.”

“Hey? Why is mom always filming Sumire?”

We, as expected, saw her pride as a professional little sister who declares it naturally.

“Hey, mom? Hey, are you listening to me?”

Kiriyama Sumire will continue to express her love for her brother. Surely, forever.

“Why are you playing BGM that I’ve heard somewhere before? Hey? Mom?”

～The End～
