Chapter 1
One morning, not long after the start of the new semester.
"Oppa, wake up!!! Mom says it's time to eat!!!"
Se-young, the youngest, was waking Si-woo up by pouncing on him while he was still asleep in bed.
"Agh!! What are you doing?!"
Startled awake by Se-young’s sudden "splash attack," Si-woo struggled to push her off.
—He was half-asleep, but he was acting out of pure desperation—
It was a "situation" involving young men that a little girl couldn't possibly understand.
The weight of Se-young’s thighs and the sensation of soft flesh through the thin blanket were transmitted directly to Si-woo’s erect cock.
Still lying down, he quickly pulled his knees up to create distance between himself and Se-young.
"Hey! I told you not to do this, didn't I?"
Si-woo spoke with a look of urgent distress, barely prying his eyes open into narrow slits as he looked at Se-young.
"Hehe~ You won't wake up unless I do this, Oppa."
Se-young laughed innocently, as if she had no idea about a man's "situation."
Seeing Se-young leaning her small chest against him, her lower body slightly lifted by his knees, Si-woo felt blood rush to his member once again.
"Hey! Get off!"
Si-woo shoved Se-young to the side.
Phew, that was a close call.
Si-woo thought to himself, catching his breath.
Having been pushed aside, Se-young now began tugging at the blanket Si-woo was covered in with both hands.
"You have to get up, Oppa! Mom told me to wake you up! I’m going to keep bothering you like this until you get out of bed!"
"Alright, alright! I get it! I'm getting up!"
Si-woo curled into a ball on his side, turning his back to Se-young as he fought to keep the blanket.
He didn't want her to see his erection.
—Though it might have been too late for that—
Se-young started shaking the blanket back and forth again.
"Don't you dare go back to sleep, Oppa~"
"I said I got it! I'm really awake! I'll get ready and come down, so please!"
With a look like he was about to cry, Si-woo sat up and hugged the blanket tight to ensure it wasn't taken away.
"You're really awake, right? Hurry down~ Breakfast is your favorite: egg rolls and stir-fried sausages."
Watching Se-young head downstairs with a little devilish grin, Si-woo finally managed to catch his breath, but his swollen cock showed no signs of subsiding.
Se-young had just entered the 5th grade at the parallel world's Beginner Academy.
While her spoiled way of speaking and her expressions remained the same, her body could no longer be considered that of a mere child.
She wasn't fully developed like an adult yet, but she had a girl's physique that possessed a precarious precociousness—as if she were perfectly poised to transform into a woman at any moment.
156cm.
She was quite tall for a Beginner Academy student.
Perhaps because she took after their mother, her proportions had been good since she was little.
On top of that, both her face and personality were lovely.
It wasn't even an exaggeration to say that Si-woo already felt a murderous intent toward her future boyfriend.

After Se-young left.
By the time he had repeated the national anthem three times in his head, his erection finally seemed to calm down.
Si-woo’s room and the room of the second sister, Se-hee Noona, were on the second floor.
The first floor consisted of the master bedroom, the youngest Se-young’s room, and the room of the eldest, Se-jin Noona, who was currently away living on her own.
After a quick wash in the bathroom in front of his room, Si-woo headed down to the first floor.
When he arrived, Se-hee Noona and Se-young were already sitting at the dining table.
His mom was sitting on the living room floor with sewing tools spread out, stitching a blouse from Se-hee's academy uniform.
It looked like a button had fallen off.
"If a button fell off, you should have told me sooner! How could you just throw it in the laundry basket like that? Do you know how busy I am in the morning?"
It seemed his mother’s nagging had begun.
"I just forgot to mention it~"
Even while eating at the table, Se-hee Noona turned her body toward Mom with an apologetic look.
"I’ve told you so many times to clean your room, but you never listen. You just buy all these clothes and cosmetics and leave them lying around, hm? You're so disobedient, so why should I be nice enough to sew your buttons on when I'm so busy in the morning?"
"I'll clean it later~ I've just been out of it lately because I have so much going on~"
"What could you possibly be busy with when you quit sports? And why did a perfectly fine blouse button suddenly pop off? Are you gaining weight lately?"
"Oh, Mom, it's not like that! Why are you saying that while I'm eating breakfast?!"
Noona spoke to Mom with a hurt expression.
Se-hee Noona, who was a first-year at the parallel world's Advanced Academy this year, had been doing track and field until last year.
She had never missed a single early morning practice and had won several awards in competitions, so she was considered a rising star by the academy and the athletic community.
But upon entering the Advanced Academy, she had suddenly decided to quit.
Since it wasn't long after their father had passed away, their mother’s worry was immense.
It wasn't that Se-hee Noona had definitely decided on a career in sports.
However, when someone suddenly quits an activity they were so diligent in, it’s natural to link the reason to the sense of loss from losing a father.
—Fortunately, there was another reason—
According to what Si-woo later heard privately from one of Noona’s friends, it was because her breasts and hips had become too large...
Because her breasts and hips were too big...
Si-woo stole a glance at his sister.
Wearing just a thin t-shirt, her physical development was certainly extraordinary.
Those soccer-ball-sized breasts on her slim, athletic body were constantly being suppressed and squeezed by her academy blouse, as if they were ready to pop the buttons at any moment.
—In fact, it seemed she actually had popped one yesterday—
The curve of her large hips connected to her narrow waist was a physique rarely seen in Easterners.
This was definitely the maternal genetics at work.
One only had to look at their mom or aunts to confirm it.
As if proving that such blessed genes could be developed to this extent through exercise, Noona sat there in all her glory.
Her reddish bobbed hair hung slightly over her shoulders.
It was a sophisticated style, parted to the sides without layers, leaving her forehead clear and open.
With her tanned, bronze skin and well-defined muscles from head to toe, she gave off a refreshing and healthy vibe.
As Si-woo sat down at the table, he casually joined the conversation to tease her.
"To be fair, it does seem like Noona’s been eating a lot lately."
"What was that? I eat the same as I always have," Noona said, glaring fiercely at Si-woo.
"Exactly. You aren't exercising anymore, but you're eating as much as you used to. Of course you're going to gain weight~"
Si-woo picked up his spoon, speaking while avoiding her piercing gaze.
"Hey! This isn't fat! It's just natural weight because my breasts are getting bigger!! I still go jogging in the morning and do my own workouts, okay? You're the one who should stop doing weird things all night and oversleeping."
Noona’s voice rose.
"Stop it, both of you!! Se-hee! Why do you keep shouting at your brother?"
As the volume increased, Mom stepped in to arbitrate.
"Ugh! It's because Si-woo keeps teasing me about getting fat!"
"To me, it doesn't sound like teasing. He's just saying what he thinks," Mom replied.
"Exactly, exactly! I'm just saying~ Hehe," Si-woo added.
"Ugh, look at him being so annoying! Mom, why do you always take Si-woo’s side even when he acts like that? Hmph!"
"Goodness, who's taking sides? Si-woo, you stop pestering your sister too!! Why do you keep provoking her?"
"Alright, alright, hehe."
"And you, why did you oversleep again today?"
Mom’s nagging shifted from Noona to Si-woo.
After the nagging continued for a while, Mom finished the sewing, stood up, and handed the clothes to Noona.
"The older siblings should set an example for the youngest! My goodness~ our Se-young is the most mature of all. She doesn't oversleep and she listens so well~"
When Mom stroked Se-young’s hair, Se-young gave a happy "Hehe."
Dissatisfied with the sight, Noona pouted and spoke up.
"That’s only because Se-young’s been sleeping with you every night lately, Mom."
Since their father passed away, Se-young, a 5th grader at the Beginner Academy, had been sleeping by Mom’s side more frequently.
While the loss was hard on the whole family, it seemed to manifest most clearly in Se-young, the youngest.
"Ah~ so it's 'mature' to leave your own room and sleep with Mom even though you're in the 5th grade of the Beginner Academy," Si-woo remarked, as if Mom’s attitude was unfair.
"Oh my~ Si-woo, you used to sleep while touching Mom’s breasts until you graduated from the Beginner Academy. Now that you're all grown up, are you going to talk like it's someone else's business?"
Mom, seemingly displeased with Si-woo’s sarcastic tone, immediately exposed his past.
"Gah! Seriously! That was only occasionally when there was a scary movie on TV back then. And I didn't touch your breasts on purpose; my hand just brushed them in my sleep!"
Si-woo was genuinely flustered as Mom dragged up his "dark history."
"Pfft, what a loser," Noona said with a look of disdain.
"Hehe~"
Se-young was still smiling with that innocent expression.
"Alright, you kids hurry up and eat so you can get to the academy~"
Mom sat down at the table, smiling brightly as if she found Si-woo and the girls adorable.
