Stay With Me Longer
Na-eun Jeong's high school had also entered summer vacation.
Along with that, our tutoring sessions changed to meeting every morning at 9 a.m. on Sundays, Wednesdays, and Saturdays, just like back in February.
No, it went beyond just changing like that...
"You want me to tutor Na-eun more?"
"Would you mind? She seems to study harder when you're around than usual."
The request came to increase the days even more. From Seung-min Jeong's parents—Na-eun's parents.
I couldn't refuse, having received favors from them and knowing they treated me almost like their own child.
From their perspective, they must have been truly desperate.
Seung-min got into university through physical education admissions, and even that took nine practical exams until regular admission. They probably wanted Na-eun to have an easier time with her entrance exams.
In that sense, they asked me, and knowing their feelings well, I had no choice but to agree.
"Sure, I can do that. Should I come every day?"
"We'd be grateful if you did. The money..."
"No need for extra pay."
"No, we have to pay more. Look how much Na-eun's grades have improved thanks to you."
It was embarrassing to hear, but honestly, it was more Na-eun's own hard work than my great teaching.
My shortcuts and problem-solving tips must have helped, but turning them into her own knowledge was all her effort.
Besides, I was already getting paid quite a lot for what was practically free tutoring.
If I lived alone, it would cover rent and food entirely.
And now more money? My conscience wouldn't allow it.
"I won't take extra. What you've paid so far is already too much for me."
"No, you're covering three subjects—this is the least we can do."
"It's not. Na-eun worked hard for it."
"...Thank you so much, Seonwoo."
"I'm the grateful one. You trusted someone as lacking as me."
"Nonsense, you're not lacking. You and Jisoo Kim are both much smarter than our Seung-min."
Ironic that I couldn't deny it.
Damn, Seung-min. How many disappointments have you given your parents? You're really the worst.
Looks like I need to properly scold him during tonight's gaming session. Time to teach him what intentional trolling is.
...Anyway, that's how I ended up agreeing to tutor Na-eun every day during this vacation.
"Really? Every day together?"
The way she phrased it sounded a bit off, but yeah, basically.
"That's the plan."
"Yesss~!"
Na-eun clenched her fist and shook it wildly, looking adorably excited. Was studying with me that great? Not gaming or playing?
"Doesn't mean you can slack off, got it?"
"Yes~"
"Good. Then let's add social studies electives to the subjects."
"Social studies? Oppa, do you know those subjects?"
No, I didn't. But...
"I can at least supervise."
I could watch to make sure she solved problems properly.
Na-eun giggled and nodded.
"Got it, please do."
Nodding along with her, I started studying with Na-eun.
And exactly two hours later.
"...Oppa."
"Yeah, Na-eun."
"Um... sorry, but... can we study at a cafe...? It's so hot..."
Na-eun surrendered, sweating profusely. It really was scorching. Her hair was messy, clothes disheveled—she clearly didn't notice. And that glimpse of intimate clothing? Best to pretend I saw nothing. I must.

Just in case, I asked Jeong Na-eun's Mother... Auntie.
With less than three minutes before a reply from Auntie, permission granted, I headed back to tell Na-eun the good news.
"Na-eun, Auntie said cafe studying is fine."
"Really...? Mom okayed it?"
"Yeah, she did."
Na-eun's face lit up, then she nodded and stood right away. And then...
"...Um, Oppa."
"Yeah, Na-eun."
"Sorry, but... can I... um... shower first...?"
A perfectly normal request from a high school girl.
Yeah, asking her to go out covered in sweat would be unfair.
I nodded, and Na-eun glanced cautiously before heading to the closet.
The moment she did, I shut my eyes. She was probably getting a change of clothes.
And those would surely include her underwear.
That embarrassingly private underwear not meant for others' eyes.
-Slide-
-Rustle rustle-
-Slide clack-
The closet closed, but I kept my eyes shut. I couldn't see the underwear in her hands.
But oblivious Na-eun asked me, eyes squeezed tight.
"...Seonwoo oppa, why are your eyes closed?"
"Huh? Oh... uh... well..."
"You can open them."
"That... clothing in your hands...?"
"Yeah, but...... umm..."
Na-eun hesitated, then mumbled something full of doubt to my closed eyes.
So quiet and slurred it perfectly fit "full of doubt."
"Se... Seonwoo oppa........."
"What...?"
"N-n-nothing!!"
-Creak!-
-Bang!!-
Na-eun flung the door open and slammed it shut after fleeing.
Only then did I open my eyes.
Of course, I couldn't recall what she'd mumbled. Too faint and garbled.
But one thing was clear: Na-eun was extremely embarrassed at the end.
What on earth did she say to get that shy?
-Thump! Thump! Thump! Thump!-
My heart's pounding too hard. Dizzy from it all.
I said it. Blurted out something so embarrassing.
'It's fine if it's oppa seeing it,' or whatever—that makes me sound like a total slut.
I know guys like naughty girls, but I don't think Seonwoo oppa is some pervert like that.
If he were, it'd kinda be even better... but based on my image of him, he's not the type.
He's seen my chest a few times, but just glances, never leering.
Saying it's okay for such a Seonwoo oppa to see my underwear? Worst mistake ever.
But it's my true feelings. I want him to see. To look and desire me.
This huge chest that draws all the boys' dirty stares—I want Seonwoo oppa to see it himself.
The mature underwear hugging this chest, my body—see it all.
If it's Seonwoo oppa, he can claim every part of me. That'd make me happier.
"Haa... Seonwoo oppa...."
I whispered his name softly, inaudible to him in my room.
Heart racing. Just saying his name heats me up, fills me with joy.
Having study time with him every day? Pure bliss.
In that time, I'll burrow deeper into his heart.
I can feel it. One foot's already in.
So confident. In this remaining month and a half, slipping fully in will be easy.
But still so anxious. Hate it.
After that month and a half, Seonwoo oppa returns to Jinhan University, and I'll be back at high school, studying without seeing him for months.
Worst case, even if I get into Jinhan University, he might be dating someone else.
No, I hate that.
This summer vacation is the turning point.
I'll capture his heart somehow. Whatever it takes, make him mine.
If not fully sure... I'll cling.
Even into second semester, beg him to tutor. Once a week is fine—just stay by my side.
I like him that much. Desperately, staking everything.
I won't give up. Never.
