Chapter 51: Chapter 51

It’s the day for the second group project meeting.

Before heading out, I double-checked to make sure I hadn’t forgotten anything.

Looking at my complex problem-solving, I suddenly felt uneasy.

I was a bit worried about whether we could properly wrap up today’s meeting.

I, as the group leader, had prepared thoroughly in advance, even as a way to prep for the finals, but what about the other members?

In particular, Jang Min-hyuk and Seo A-rin, who Shin Ah-young said were not that trustworthy.

The content’s only going to get tougher, and if they can’t even understand today’s material, they might just give up.

I shook off the negative thoughts and stepped out the door.

Nothing’s going to change by worrying about it now, just gotta trust the process.

Once I hit the streets, the lush green trees and grass were sprawling everywhere.

Mid-May, each day visibly greener than the last.

I dodged the sunlight as much as possible, sticking to the shade on my way to the café.

Ting-a-ling.

As I opened the door and entered, someone was sitting in the same spot as last time.

I could only see her from the back, but the long black hair and the side-profile of her massive tits made me think it was Shin Ah-young.

I hesitated for a moment.

Should I sit next to Shin Ah-young, just like last time, or face her directly?

Three of the four seats were empty, and it might seem weird to just plop down right next to her.

With these thoughts, I approached the table.

She glanced sideways as she heard me coming, and our eyes met.

「Hello, you’re early today.」

「Hello, I was the last to arrive last time, so I came early today.」

After a brief greeting, I sat diagonally across from Shin Ah-young.

Seeing her in person, my confidence to sit directly across had long vanished.

She had already laid out her study materials in front of her.

I pulled out my books from my bag and casually asked,

「Wasn’t the material tough this time? I struggled a lot with it.」

「I couldn’t solve it either, but then a good idea suddenly struck, and I managed to figure it out.」

「Well, good thing you managed to solve it.」

Back to silence.

With about 10 minutes left until the scheduled time, I waited for the rest of the group members while looking out the window.

A moment later.

I could see a man and a woman walking towards us in the distance.

As they got closer, I recognized Jang Min-hyuk and Seo Ah-rin.

Soon the door opened, and a familiar voice followed.

「Hello! We are here.」

「Hello.」

Jang Min-hyuk sat next to me, and Seo Ah-rin next to Shin Ah-young.

Once everyone was gathered, I opened my mouth.

「Shall we start by ordering some drinks?」

「Yes!」

「Sounds good.」

「Okay.」

As we discussed what to order, Jang Min-hyuk and Shin Ah-young, seated on the outside, went to place our orders.

I turned back to the window, trying to zone out, when Seo Ah-rin asked me a question.

「Um, group leader, have you solved all the problems?」

「Yes? I’ve solved them all. Did you have trouble?」

「Yes… I tried repeatedly but got stuck at a specific part.」

「That’s okay. I’ll explain it later, so you can learn it then.」

「Oh, thank you!」

Her tense face relaxed.

Honestly, the difficulty was high enough to struggle alone.

All I hoped was for them to review and keep up, even if they couldn’t solve everything.

Soon the coffee arrived, and after a few sips, I looked at the other members.

Just by their expressions, I could tell the situation.

「Shall we start? Please bring out what you’ve studied.」

Rustling sounds as notebooks and A4 papers were laid on the table, and Jang Min-hyuk, with a hesitant voice, spoke up.

「I’m really sorry, but I got stuck halfway and couldn’t finish.」

「That’s okay. Just review what I show you, no pressure.」

I started with the notebook of Jang Min-hyuk sitting next to me.

Despite the difficulty, it seemed he had thought deeply about it as several symbols were intricately arranged.

I read through his solutions from the beginning.

He was solving it well until he suddenly got stuck.

It was the same part Shin Ah-young had struggled with a few days ago at the café.

This clearly was a killer part.

「This part is tough. But you got everything right up until here. You’ve put in a lot of effort.」

His expression, tense as if undergoing a test, relaxed.

I offered him light praise and turned my head forward.

Next was Seo Ah-rin’s turn.

She was also stuck on the same part.

However, she had gotten everything right up until the problematic section, so I gave her the same encouraging words.

Lastly, it was Shin Ah-young’s turn.

Though I already knew she understood everything, I pretended not to know and opened her notebook.

Her handwriting was neat and well-organized.

I was immediately impressed by the clarity.

To check if she had understood everything I had taught, I read through her work carefully.

Unlike the others, she had moved past the difficult section and had written down the correct answers.

「You got it exactly right. You really did well.」

I gave her a thumbs up and waved my hand in praise.

Suddenly, she looked into my eyes and then down at her hands with a vacant expression.

「Uh… ah! Yes! Sorry, just reminded me of something from the past.」

Her apology came with an ambiguous remark.

I held her notebook while asking for permission.

「Can I explain using this? Your handwriting is so clear, it’s easy to follow. Mine is a bit sloppy.」

「Yes, go ahead. I’m fine with it.」

With her permission, I placed the notebook on the table so everyone could see and started explaining mainly to Jang Min-hyuk and Seo Ah-rin.

「It seems you both got stuck here, but first, look at this circuit, here and here…」

Both looked clueless at first, but after several repetitions, they began to understand.

「Wow! So that’s how it works. How did you even come up with this? Genius?」

「I never thought of using this formula here. Wow.」

Amazed, they began to hastily copy the information into their own notebooks.

I gave them some time and then looked at Shin Ah-young.

She had been quietly observing the explanation, probably because she already knew, but the questioning look on her face made me speak up.

「Do you have any questions? Even if you solved it, anything confusing?」

「No, I know it all… But the solution is exactly the same. Just like your explanation.」

I felt a twinge of guilt.

Of course, it would be the same; I had taught her after all.

In hindsight, I might have focused too much on the explanation to avoid suspicion.

But she would never guess I was practically a ghost here, though it seemed I had at least sparked some doubt.

「Well, we’re just applying what we learned upfront. Your solution was just like mine.」

「That’s… true.」

「Just used the standard formulas from the internet and books. It’d be stranger if I knew any different solutions. Not like I’m a professor.」

「…That makes sense. I just asked because it was exactly like how I solved it.」

Her voice was somewhat unconvinced, but it seemed her doubts were somewhat alleviated.

I turned back and took another sip of my coffee.

As reality began to intertwine more, the chances of getting caught increased.

I’d have to be careful about small habits or actions in the future.

Thinking about what precautions to take, the rustling noises stopped.

All my group members were looking at me, as if asking, 「What now?」

「Try solving it here, and if you get stuck, ask again. After we’re done, I’ll tell you what we’ll study next.」

Including Shin Ah-young, everyone began working on the problems again.

I leaned back in my chair and resumed my thoughts.

If I don’t cut this off now, it’ll snowball.

Maybe I should use the avatar mode here?

If they saw a ghost and me together, they’d probably drop all suspicion.

As a decent idea popped into my head, I decided to give it a try.

I crossed my arms, making sure not to lose my posture, and closed my eyes.

I slipped out of my body and first went into transparent mode, moving closer to Shin Ah-young.

There wasn’t much time, so I started looking for a quick way to finish this.

Obviously, I couldn’t just drop my pants and start humping here.

A blowjob would require opening her mouth wide, which would definitely get noticed, and a titjob was out of the question with her tight T-shirt;it’d be too shaky.

As I rummaged through my brain, I remembered the last time Yoon Hye-yoon had just unzipped and masturbated.

I slipped under the table between Shin Ah-young’s legs.

Then, I activated the translucent mode.

When I appeared below, she was startled and her eyes went wide.

I waved my hand and then unzipped her pants.

Her black panties, clinging tightly to her skin, appeared and I touched a finger to them.

She tried to cross her legs, making an X with her fingers under the table to stop me, but it was futile with me in the way.

I pushed the panties aside and moved down along the bare skin.

When my fingertip reached her round clit, I began to rub it quickly.

She could bear this level of pleasure, so while keeping an eye on the others, she returned to solving the problems.

I increased the pace from the beginning, aiming to finish quickly.

As her clit hardened slightly, her lower abdomen started to twitch.

Without stopping, I continued, and soon after, she clenched her stomach muscles and subtly finished.

I withdrew my hand and turned off avatar mode.

Returning to my original body, I maintained my position and stayed still.

「I’ve solved it all now! It’s starting to make sense.」

「Me too.」

「I’ve solved it all too.」

With slightly flushed voices, the group signaled the end of the session. I unfolded my arms and opened my eyes.

I spread the textbook in the middle of the table and started explaining.

「That’s as far as we’ll go for the next session. It will be tough, but even if you can’t solve it, don’t skip and please come. That’s it for today.」

「Great job everyone!」

「Good work.」

「Thank you for your hard work.」

As we wrapped up today’s session, everyone began packing their bags.

The table cleared, and we sat sipping coffee for a while.

It was awkward to start a conversation.

Should we chat, or should I just grab my coffee and head home? Just then, Seo Ah-rin broke the silence.

「Ah! Ah-young. This might be a bit sensitive, but can I ask you something?」

「Uh? Yeah, sure. What is it?」

「There’s been a rumor going around school… did you break up with your boyfriend?」

I wasn’t sure if it was appropriate to ask, but the concerned party herself seemed calm.

「Yeah. We broke up. Just didn’t feel right.」

「Oh, I see. Sorry.」

「It’s okay. And I’ve found something better now, so it doesn’t matter anymore.」

「Oh? Did you find someone new, or are you declaring singlehood?」

「That’s… a secret.」

She smiled slightly, then took her coffee and stood up.

「I’ll head out first. Great job today, everyone.」

She made eye contact with each of us before leaving the café.

It felt awkward to stay any longer, so I also wrapped things up.

「I’ll be going too. Great job today.」

「Thank you, leader!」

「Good work.」

They seemed to be planning to stay a bit longer.

I left the café and headed straight home.

But it’s the weekend… do I have to stick around with Shin Ah-young again?
