My Younger Sister Was My First Love

62. Do It

It’s not like watching AV makes everyone a rapist, nor does playing games make everyone a murderer.

Just because they’re addicted to Ince#stuous content and imagine wild scenarios with family members, it doesn’t mean they’ll actually fall in love with their family in real life.

– Buzz buzz buzz –

As always, we returned home as if nothing had happened.

After the intense kiss in the classroom, Jihee didn’t take any further action.

She just held my hand and said it was enough, and we left school.

I lay powerlessly on the bed after taking a shower.

Since I hadn’t drunk a single drop of alcohol, every memory was vivid and clear like a 4K video.

We kissed.

At school.

With my sibling.

Jihee’s kiss, which was as ridiculous as being called on stage as a celebrity, was giving me a painful pleasure.

There are stages in a normal romantic relationship.

There’s no set formula, but it’s what people usually do.

Two people who were strangers become closer, holding hands, hugging, and kissing.

From strangers to some, from some to lovers.

But surprisingly, Jihee and I didn’t develop anything on the surface.

[Family → Family → Family]

Whether we held hands or kissed, it was all the same.

No matter how outrageous our actions were, we couldn’t escape the ‘family’ framework.

If we assume that the ultimate goal of lovers is to become a family through marriage, then we were playing a game that started from the max level.

The more I thought about it, the more absurd the logic became.

I scratched my head at the ridiculous idea.

But one thing was certain – the more we did this, the more I was drawn to Jihee.

It wasn’t about right or wrong, good or bad; it was about the layers of time we spent together.

Humans aren’t machines that only operate with reason.

Jihee’s existence was gradually entering the realm of ‘irrationality’ within me.

Sometimes when I talk to Minju, I feel an unbearable sense of reality weighing down on my shoulders. But when I’m with Jihee, it’s like I’m dreaming, and everything feels hazy.

Is Teacher really not human?

Maybe Jihee is a divine being sent to test me, a devil of trials.

The trials didn’t end with yesterday; they continued to the next day.

* * *

The second day of the festival went by peacefully, just as I had promised Minju.

“Iljunho!”

My name was called more frequently than necessary today, all because of the stage incident yesterday.

It seems the footage has spread online.

My embarrassed face was exposed to the whole world.

Even Jihee’s face, caught on screen for a brief moment, was a hot topic.

“Hyung, didn’t you abandon us and go have fun with a girl?”

“You’re counting the time I watched with my dongsaeng as going to have fun with a girl?”

“How was it when you saw her in person? It was ridiculous.”

“You guys saw it too. She was really pretty, what’s the big deal.”

“Did you not shower? If I were you, I wouldn’t have showered either.”

Honestly, Jihee’s deep kiss left a 100 times stronger impression than any casual peck.

“Hyung, aren’t you going to play with us today?”

“I have to go home.”

“Dongsaeng?”

Slowly, the people around me were adapting to my lifestyle.

“Yeah, I promised to study with them.”

“Ugh… do we have to do that until the festival?”

“It’s a festival for us, not for them.”

“If Jihee’s college entrance exam doesn’t go well, won’t you cry together with her?”

Hmm… I hadn’t thought about that before.

If Jihee’s entrance exam doesn’t go well, what kind of feelings would I have?

I’d probably feel a huge sense of responsibility, but I wouldn’t cry.

I didn’t cry when I failed my own entrance exam, so it’s weird to cry just because Jihee failed.

And to be honest, I didn’t think it was a big deal.

Getting into a top-tier university like Seoul National University seemed achievable, even if it wasn’t a perfect score.

“I won’t cry.”

“Then are you leaving now?”

“Yeah, I’ll go first.”

“Alright, bye!”

I parted ways with the kids and boarded the bus, leaving the crowded school behind.

As I stopped by the supermarket to buy some snacks on my way home, I slowly bent down to pick up a small package box left in front of my door.

What is this? I didn’t order anything.

The era of fast delivery has arrived.

Now, if you order something, it arrives on the same day, an astonishing era has begun.

It wasn’t a mistake that the delivery was made.

The name written on the recipient’s field was Teacher Dong’s three-character name, written correctly.

It was labeled as office supplies, but they were office supplies that Jihee needed.

I was curious about what was inside, wondering if there was something unnecessary.

I brought the box to my ear and tried to guess the contents by the sound.

-Thud thud

It didn’t feel like a heavy object, not like a pen or something.

Still, I didn’t have the bad habit of carelessly opening someone else’s package, so I entered the password and went inside.

Jihee still had time to study.

I put down my bag, changed my clothes, and neatly placed Jihee’s package on the table in front of the sofa.

I’ll ask her what it is when she comes out.

It was about an hour later that Jihee came out of her room.

I was preparing dinner at the time.

“Oppa!”

She was wearing a black boxy tee and purple pajama pants, a usual combination, but today it seemed like there was something on her mind.

“What’s for dinner?”

“Grilled pork belly with stir-fried vegetables.”

“Oh, perfect for drinking.”

“But we can’t drink.”

“Did I say I’d drink?”

Jihee pulled out a chair and sat down, asking me questions like a mom asking about her child’s daily activities.

“Was the festival fun?”

“I didn’t go. I just attended the lesson and came back.”

“Did you miss me?”

Jihee covered her face with both hands, making a flower shape.

“That’s not it. I just didn’t see the point in staying longer, so I came back early.”

As I was stirring the pan with a spatula, I suddenly remembered the package and brought it up.

“Ah, right. I saw the delivery earlier.”

“Delivery?”

“Yeah. I left it on the table over there.”

“Really?”

Jihee got up from her chair and walked over to the table, picking up the box and coming to stand next to me.

“Did you see what’s inside?”

“No? I just saw that it was labeled as office supplies.”

There was no response.

All I could hear was the sound of the tape being ripped off from the side.

“Zip!”

It seemed like the meat was fully cooked, so I glanced to the side, and an item far removed from school supplies, a silver handcuff, was in her hand.

“What’s this?”

“Handcuffs.”

“So, why did you buy that?”

“I needed it.”

“Handcuffs?”

I couldn’t fathom why my re-taker younger sister would need handcuffs.

“Yeah.”

“Where?”

“Where, exactly?”

Jihee slyly grabbed my wrist and put the silver ring on my arm.

“Here.”

“…You’re going to put this on me?”

I had seen kids playing with toy handcuffs when I was young, but it was quite embarrassing to be playing with real handcuffs as a grown adult.

“Will I get locked up?”

When I reacted with disbelief, Jihee put the handcuffs on her own wrist and opened the ring with a click.

“Who’s supposed to wear this? No, wait. Why did you even buy this in the first place? What a waste of money.”

“It wasn’t expensive. It was only 20,000 won.”

“20,000 won is still money, isn’t it?”

“Anyway, I just wanted to buy it.”

It’s their personal freedom to spend their own allowance however they want.

It was a ridiculous situation, arguing about whether it was okay to wear handcuffs as a form of self-education, and not something that violated the law or was an explicit adult product.

“It’s fine if you want to play with it, but don’t put it on me or lose the key.”

“Can’t I lock it?”

“No.”

“Then can I put it on just one wrist, like a bracelet?”

Her eyes sparkled like a child’s, pleading to wear the handcuffs.

It was burdensome to see her making such a request with her big, round eyes.

“Don’t you dislike it?”

“Be mean to me!”

“It’s weird for an older brother to say he’ll wear handcuffs on one wrist, isn’t it?”

There’s no way a sane person would say something like that.

“I think I’d just stay still even if you locked me up for a whole day.”

“You’re the weird one.”

“If you put it on my foot, I’ll forgive you.”

“Stop it. You’re really weird.”

“So, you like weird people, older brother?”

When I turned my head, Jihee giggled and put the handcuffs on my wrist again.

“Ah. Sorry. I’ll correct it to ‘liked’.”

“……I didn’t know you were that kind of person back then.”

“Huh. If I had known your personality, I wouldn’t have liked you.”

It’s a strange question.

If I had known Jihee’s personality in middle school, would I have not liked her?

Jihee’s first impression was that of a cold and quiet kid.

In school, she always wore earbuds and stared at her phone, so even if there were people who wanted to get close to her, she wouldn’t give them a single glance.

That’s why I always watched her from behind, quietly observing her.

But I never thought she’d become my sister-in-law and be like this with me……

“I don’t know.”

“I don’t know either. You probably would’ve liked me anyway.”

Honestly, I somewhat agree, so I didn’t bother refuting it.

If I had judged her based on her personality, I would’ve done it already.

Looking at my current situation, Jihee’s words might be right.

“Let’s eat.”

“Okay!”

As we took out the side dishes from the fridge, Jihee served me rice from the side.

“I’ll eat well!”

“I’ll eat well!”

Even during the meal, my eyes kept drifting to the handcuffs on the table.

What was she planning to do with those?

“Is Unnie Minju coming tomorrow?”

Was she going to show them off to Minju?

“Yeah. Just in case, don’t take those handcuffs out when Minju is here.”

“Huh. Why not?”

“You might misunderstand again.”

“Didn’t we play with handcuffs as a joke in school, oppa?”

Jihee put on the handcuffs, spinning them around with a straight finger.

“It’s just a toy. A toy. Why do you keep thinking weird things?”

I don’t know.

Not knowing what to do was even more terrifying.

Maybe when I woke up tomorrow morning, my hands would be tied up.

“You don’t need toys for studying. When Minju comes, put them away in my room.”

“Okay.”

Since she accepted it so readily, it didn’t seem like she was planning to prank Minju. Hmm……

The question remained unanswered, and the meal ended. Jihee returned to her room to start her last evening study session.

I lay down in my room, playing games on my phone, and went out to the living room to watch TV around the time I was supposed to receive a call.

It would be out soon.

What part was it today, anyway?

Was it a series?

As I was thinking about the tips related to the series……

“Oppa!”

I heard Jihee’s desperate voice calling me from inside her room.

Since she seemed quite urgent, I got up from the sofa and headed towards Jihee’s room.

“Why.”

“Help me!”

“What’s going on? Are you going in?”

The moment I opened the door without knocking.

“……What are you doing?”

It was difficult to comprehend the situation at first glance.

Her pure white skin was fully exposed without any mosaic processing.

Jihee was currently wearing only a black lingerie.

From there, something was severely wrong.

“Ah, I… I dropped the key.”

As soon as I mentioned the key, I looked towards the bed and saw Jihee’s left wrist was handcuffed to the wooden bedhead.

“Why did you put that thing there?”

“I paid 20,000 won for it, so I have to use it, right?”

“That’s not it. No.”

How could I understand my sibling, who was handcuffed to the bed in lingerie?

“Oppa, I know what you want to say, but can you just pick up the key for me? I want to get out of this.”

“Where did it fall?”

“There.”

Her uncuffed hand pointed to a tiny gap behind the bedhead.

It seemed to be deep inside the mattress and frame, making it quite difficult to retrieve from the bottom.

It seemed like I had to insert my hand from the top to get it out.

Considering Jihee was tied up here, it was uncertain if this was realistically possible.

“Just a minute. I’ll get something like a stick.”

“Why?”

“What’s the point?”

“It’s okay if Oppa just gets on top of me.”

“Do you want me to get on top of you in this state?”

It was inevitable.

We would have to make contact with a huge area of skin.

It was as if we had to be glued together.

“I’m fine, Oppa.”

As Jihee tried to move her arm, the handcuff chain made a rattling sound.

With her legs crossed, Jihee, who resembled a captured war prisoner, looked at me with a desperate gaze and uttered a single phrase.

“Do it.”

……So you’re saying that’s really weird.
