Help! I'm Being Blackmailed by a Suspicious Person!
"Of course. Come into my classroom for a moment."
"...Yes!"
Class 2's teacher opened the classroom door more readily than I'd expected.
Thank goodness.
Min Yu-ha followed Han Tae-oh into Class 2. The room was empty.
The kids must all have gone home.
"Have a seat here."
"Thank you."
Screeech.
Kindly enough, Class 2's teacher pulled out a chair for her. She sat down demurely in front of him.
Being here like this... it almost feels like I'm a real student consulting my homeroom teacher....
Class 2's teacher spoke first, in a calm voice.
"What's going on?"
"W-well, um...."
"I've noticed you haven't looked well lately. Se-hee mentioned it, and I've felt the same."
"Oh... R-really...?"
Ugh... he's even been watching my expressions.
"What could be troubling you?"
"W-well.... Um...."
She swallowed hard. She glanced at Class 2's teacher's face.
I have to tell him... ask for help. From Class 2's teacher...!
Her resolve was firm, but the words wouldn't come out easily.

"Is it something serious?"
"Y-yes? Y-yeah... w-well...."
What do I do.... Did I make a mistake saying anything...!
His relaxed but sharp gaze made it impossible to speak.
Class 2's teacher was so kind... always helping with even small things. And earlier that morning, he'd pretended not to notice her panties.
Maybe if I tell him I'm being blackmailed, he'll understand?
That impulsive thought had made her approach him....
'The truth is, I posted naughty photos online, got caught by someone, and now they're blackmailing me! ...How could I say that to his face...!'
Regret came too late.
To explain, she'd have to expose her own shameful secrets.
Her perverted, embarrassing flaws.
'Of course, Class 2's teacher is such a good person he'd try to help if I asked....'
But in the process, he'd see everything she couldn't bear to show.
Her nude photos. Her secret account. Even the fact that she'd secretly taken lewd photos at school.
...How could I tell him that...! Min Yu-ha, you idiot. Dummy. Pervert...!
"U-um...."
"If it's hard to say, take your time. Whenever you're ready. Take a deep breath."
"Y-yes....... Hoo....!"
He guided her gently, like someone experienced in counseling.
He's such an amazing teacher... Class 2's teacher.
She wanted to cry out to him.
'Help me! A suspicious person's blackmailing me...!'
But if she did... if things went wrong, that person might spread all the photos...!
Even Class 2's teacher couldn't do anything then. And the blackmailer knew she was a teacher at this school.
If something went wrong and Class 2's teacher got dragged in too....
'I can't let that happen...!'
Min Yu-ha shook her head vigorously.
She'd just been feeling so confused and exhausted, wanting some comfort, so she'd tried talking to him.
But on second thought, it was too dangerous.
It could drag a good person like Class 2's teacher into it.
No matter how hard it was, she couldn't accept that.
'I can't rely on Class 2's teacher. I have to solve this myself...!'
Steel ing her resolve, Min Yu-ha changed her expression completely.
She let out a big sigh and opened her mouth.
"Um... Class 2 teacher, I'm really sorry, but I don't think I'm ready to talk yet."
"I see."
"C-can I consult you next time...?"
"Of course. Whenever you're comfortable. Just let me know."
"Thank you so much...! Class 2 teacher."
Min Yu-ha jumped up and bowed deeply.
Calling him over just to say "next time" was ridiculous, but he accepted it without a hint of annoyance.
"Then, whenever you're ready to talk next time."
"Yes.... I'll ask you then!"
Min Yu-ha bowed once more and fled the classroom.
There wasn't much time left until "Master" had ordered her to arrive.
'First, I need to follow his orders and gather more clues. Even if it's just me...!'
She pondered everything that had happened so far.
Every morning, she'd done as told: removed her underwear and put it in the mailbox. When she checked after work, it was always gone.
Today's underwear, which she'd left that morning, was already missing by lunchtime—she'd checked just in case.
So someone was taking it. But who?
It was unlikely anyone else would. People didn't check other classes' mailboxes every day.
She'd seen 3rd and 4th grade mailboxes piled with official mail and dust for over a month...!
So it had to be the blackmailer, ninety percent sure. They knew exactly when and where her underwear was stored.
Thinking about the lunchtime disappearance...
The blackmailer was either inside the school or someone who could visit daily.
Or maybe they had an accomplice here!
She considered every possibility.
Doing all this detective work made her feel like a real sleuth.
'But even so, there are still way too many suspects....'
The school wasn't just students and teachers.
Other staff, janitors, cafeteria workers, delivery people, parent volunteers, construction workers.
How to figure out who among them...?
Faces flashed in her mind.
Men at our school.... The principal, the admin head, 5th grade... that guy whose name I don't know. And.
Class 2 teacher.
The moment Han Tae-oh's face came to mind, she stopped in her tracks.
She shook her head frantically, as if in a panic.
No. No way...! Class 2 teacher would never do that...!
Her heart refused to accept it, but her head kept putting him on the suspect list.
And for good reason... They'd met often lately... especially in the office a few times....
Suddenly suggesting combined classes during no-bra lessons... and today with the panties....
The more she thought, the stranger it seemed.
There were too many connections to ignore.
No...! He's the teacher next door, of course there are connections. Idiot...!
She shook her head again.
It had to be coincidence. She was just overthinking...!
As Min Yu-ha agonized over it again and again.
Thud thud.
[Music Room]
5th floor. She'd arrived in front of the music room.
The highest floor in the annex.
No grade-level classrooms on the 5th floor—it was all special rooms.
The music room was the most remote of them.
Being so isolated was great for noise-free music lessons.
But...
If something happens here.... Who could help me?
In a situation like this, it was the worst possible spot.
That person must have chosen it on purpose, right?
You couldn't pick a place like this without knowing the school's layout intimately.
Definitely someone inside the school.
With that thought, Min Yu-ha opened the music room door.
Screeech.
"Um... is anyone here?"
No one.
She'd expected them to be waiting.
She'd arrived right on time.
What were they planning here?
More photos to take and send?
As she scanned the room, something caught her eye in the center of a desk.
"Huh...?"
Should she go closer?
An eyemask and a note.
"...An eyemask?"
She picked both up.
The note had printed text.
Put on the eyemask and wait here.
That was all it said.
Eyemask... they want me to wear this, huh?
Why an eyemask?
It didn't take much thought.
Because that person... was coming here.
To hide their identity, they wanted her blindfolded.
What did they plan to do when they met?
Hiding their face.
They wouldn't just look at her bra-less, panty-less body now....
Maybe today, I'd...
Thump thump. Thump thump.
Her heart pounded....
It wasn't excitement. If it were, her thighs would be wet.
She liked exposure, sure—but only being seen. Not meeting someone in person for... weird stuff...!
What do I do...! Help me, Class 2 teacher...!
Should she call Class 2's teacher now?
But if he saw her like this...!
She fiddled with her phone.
Call? Don't call? As she hesitated, the camera at the top of the screen caught her eye.
"Ah."
Maybe... with this...
It could work. If she did it right!
Min Yu-ha opened the camera app and looked for a spot to prop up her phone.
A position where her blindfolded self would be clearly visible.
I'll catch whoever comes in on this camera...!
Mirroring 6th Grade Class 3 Homeroom Teacher Min Yu-ha's Phone
"Hm... Teacher Yu-ha. You're more thorough than you look."
Before heading to the music room, I'd mirrored her phone just in case.
The screen showed the camera on. Location: back of the music room, near the janggu storage.
She positioned the camera to film the room and started recording.
She peeked in to check if she was in frame, nodded, then went to the center and put on the eyemask herself.
"Planning to film the blackmailer and find out who it is?"
If I hadn't checked via mirroring, I'd have been caught for sure.
Even if my identity got out, it wouldn't erase the leverage I had over Min Yu-ha.
Still, I preferred keeping it secret a bit longer.
I wanted to savor her fidgeting anxiety more.
Should I deal with the camera first when I go in?
Stop the recording and delete the video. Then...
"...Gulp."
Min Yu-ha, standing blindfolded, waiting obediently.
That pure teacher's defenseless body, no bra, no panties...!
Touching it with my own hands.
I suppressed my throbbing erection and hurried up the stairs.
Imagining Min Yu-ha's naked body I'd soon see in person.
My steps were faster than ever.
"Hm...?"
Ryu Se-hee, heading to the department meeting, suddenly stopped.
She spotted a man rushing up the stairs.
"Teacher Tae-oh...?"
Where was he hurrying up to like that?
Rattle.
"Hic...!?"
Min Yu-ha flinched at the sound of the music room door opening.
He's here. That person...!
