Backside_Of_One
After getting home, I lay on my bed and stared at my phone.
"Ugh, what am I going to do with this girl?"
When I opened the Trickster block list, a familiar nickname was right at the top.
[Backside_Of_One]
The Backside Girl who posted photos of her own naked body on Trickster.
Commonly known as Bback-sa.
I stared at Bback-sa's nickname with a complicated expression. I'd blocked her to deliberately ignore all this, but after the pointless shit I'd heard earlier, my thoughts were a tangled mess.
'People are saying they'll find her... What if something really bad happens to her?'
The truth was, I had a strong suspicion about Bback-sa's identity. I was half-certain.
'One of the club members.'
Bback-sa had given me too many clues to keep pretending I didn't know.
At first, the only person I thought Bback-sa could be was Jeong Mi-na, a ghost member and a fourth-year sunbae in Digital Content.
But after sharing a bed with Mina noona in person, it became clear she was definitely not Bback-sa. A message from Bback-sa came in right while we were going at it, so her alibi was airtight.
Naturally, the candidate pool narrowed.
By process of elimination, two people remained.
One was Han Saebyeok, the third-year from Fashion Design who'd protected Areum before.
The other was Ju Hana, the second-year from Fashion Design who'd become my mentor at the recent club meeting.
And among them, the stronger candidate was none other than...
"Ju Hana......."
It wasn't a blind guess; it was a deduction with evidence.
First of all, Bback-sa's chest was small.
That single factor ruled out a lot of people. Due to physical characteristics, neither Department Head Yu-bam nor Seora noona could possibly be Bback-sa.
Mina noona was excluded for the reason above.
Areum wasn't even worth considering.
So the remaining candidates were Han Saebyeok and Ju Hana. But looking at the photos posted on Camta, the likelihood that Bback-sa was Ju Hana grew even stronger.
'Saebyeok Sunbae has a tattoo.'
A thorn vine tattoo starting from the base of her neck.
I didn't know the exact size and length, but given it was a thorn vine pattern, it couldn't have been small. Furthermore, I'd also seen a black rose tattoo on her wrist.
But there were no tattoos whatsoever on Bback-sa's wrist or back.
Previously, I thought maybe she'd edited out the tattoos with Photoshop. It would have been a hassle, but hiding her identity was well worth the effort.
However, judging by Bback-sa's activity during this recent exam period, it looked like she'd taken and posted the pictures at school during the early morning hours. In other words, the photos went online without any Photoshopping at all.
Could you perfectly erase a tattoo with Photoshop in such a short time? I thought it was impossible. That was why I removed Han Saebyeok from the candidate list.
'Of course, she could take the pictures in advance, edit them later, and then post them.......'
The person in question was Bback-sa, an exhibitionist who even ran an alt account for this. She was probably getting off on the thrilling, precarious tension instead.
But what if that tension became reality?
Would she still be so happy about it then?
'I don't think she would, honestly. This chick's secretly a coward.'
How many messages had I exchanged with Bback-sa by now? Her messages were clearly meant to provoke me, but at the same time, a subtle, underlying fear always peeked through.
In my opinion, Bback-sa was a textbook internet tough guy. I could tell because I'd been similar. All kinds of provocations and playing tough, but on the inside, there was a heavy dose of cowardice.
'She's always teasing me and calling me a virgin, but I'm pretty sure she's a virgin herself.'
Even if you posted your own nudes online, when a situation actually arose where you were discovered or ambushed by someone in real life, you'd feel fear.
Of course, that was just my speculation too.......
'Ju Hana, who I actually met in person, also seemed tough but was the timid type.'
At first glance, Ju Hana came off as expressionless and cold. With her hair bleached yellow, she also gave off a bit of a delinquent vibe.
But once I actually talked to her, Ju Hana was the epitome of timidity. In MBTI terms, a capital I was obvious. And truthfully, if you looked closely at her expression, it wasn't cold so much as gloomy. Maybe it was just how she did her makeup, or maybe they were real dark circles, but the skin under her eyes was always hollow and dark.
I felt a certain sense of guilt and kinship toward Ju Hana. I felt sorry for inwardly misjudging her based on first impressions, and I felt a sense of kinship for how her timid personality kept her from fitting in with people around her. Though I couldn't exactly empathize with the exhibitionism, of course.
Anyway, I hoped nothing bad would happen to that Ju Hana. Above all, I was a longtime fan of her other persona, the cosplayer 'Juha'—not 'Bback-sa'.
"Sseup. I've gotta tell Hana outright."
The most effective method was telling Ju Hana directly. That I knew her identity, that it was dangerous now, so she needed to stop the crap about posting nudes on Camta.
But I hesitated.
What if I was mistaken about Hana?
What if Bback-sa's identity was actually someone else?
Then I just became the weirdo. The guy who exchanged messages with the Backside Girl and thought a perfectly normal person was some exhibitionist who posted lewd pictures. That would make it incredibly hard to look Ju Hana in the face from now on. The reason I'd blocked Bback-sa in the first place was that seeing Ju Hana always made Bback-sa's messages pop into my head, making it awkward—so this would be completely putting the cart before the horse.
In the end, I decided on the next best option.
'First, unblock her.'
I sent a message, not to Ju Hana, but to the Bback-sa account.
- Hey, I unblocked you, so stop posting pictures on Camta.
- Keep this up and you're gonna end up in serious trouble.
*
Bzzzt.
[A new message has arrived.]
[Kkang-cheol] : Hey, I unblocked you.......
"Huh?!"
Bback-sa flinched in surprise and grabbed her phone.
= Hey, I unblocked you, so stop posting pictures on Camta.
= Keep this up and you're gonna end up in serious trouble.
A floppy, goofy smile bloomed on Bback-sa's lips as she read the messages. Then she jolted and looked around furtively.
She immediately headed for the bathroom.
Cheolkeok.
After locking the door, she looked back at the messages, and her lips loosened into a grin again.
"Heuhee~. Are you worried about me?"
She immediately started typing a message.
- Pictures? What pictures?
She wasn't trying to play dumb.
She casually pulled her pants down, hiked up her top, and launched the camera app.
Chal-kak.
- These kind of pictures?
- (Photo)
She adjusted the angle so her chest wasn't visible and emphasized her slender waist. She pulled down one side of her panties to reveal her iliac crest, making her pelvis stand out prominently in the shot.
Bback-sa waited for a reply with a pounding heart.
= [The other person is typing a message.......]
Whatever he was typing, it took him a long time to compose the message.
"Is he jacking off? Did I turn him on?"
Even the time spent waiting for the message was enjoyable for Bback-sa. The smirking grin never left her lips.
= Sigh. Fine, send them to me instead.
= Seriously stop posting on Camta. You'll get in real trouble.
Seeing the message, her lips curled up.
"Euhihit. Yep, he's worried about me."
It was kind of cute that he'd gone out of his way to unblock me and send a message.
What was the big deal about posting a few nudes?
Considering how many pictures she'd posted on her alt account so far, why was he suddenly so worried now?
= You know what I heard today?
= Guys are saying they'll try looking for you to get a taste.
= You take those pictures on the spot and post them, right? In a school bathroom.
"U-eh?!"
Her shoulders, which had been shaking with laughter, jolted in alarm.
"L-looking for me? H-how did he know I took them in a school bathroom? Ah!"
A plausible reason came to mind.
'Someone must have seen the picture I took by mistake yesterday. I deleted it right away, though.'
Among the photos she'd posted on Camta, there was one where the school logo was visible. She'd realized her mistake immediately and deleted it, but it seemed someone had seen it.
Recalling the memory made her shoulders hunch inward.
A stranger was looking for her to rape her.
Just as Kang Cheol-jin predicted, Bback-sa was terrified. She clearly had an exhibitionist fetish that made her post nudes, but she by no means wanted to be violated by some unknown man.
But the worry only lasted a moment.
'How's anyone gonna find me in this huge school?'
The only thing they had to go on was that the school logo was visible. And anyway, since she posted it on the school Camta, a lot of people would've guessed it was taken on campus even without the logo.
So in the end, nothing had changed.
How many buildings and how many bathrooms were there on campus? How could anyone possibly track down one specific person?
She shed her worry just as fast as she'd gotten scared and regained her smile.
- lmao well I do have a pretty hot body. You wanna do it too, don't you?
= You crazy bitch, I'm worrying about you and you're still giving me shit? Just answer the question.
- Oh dear, is widdle Kkang-cheol worried about me?
= You're impossible to talk to. Anyway, don't do shit like posting pictures on Camta anymore. You got it?
Grinning as she continued exchanging messages, she suddenly pouted her lips. It was because Kang Cheol-jin suddenly felt infuriating to her.
'Who do you think I posted pics on Camta for in the first place?'
It was because he'd blocked her.
Of course, you couldn't call that Kang Cheol-jin's fault, but if her way of thinking had been normal to begin with, she never would've sent him her nudes in the first place.
She needed a partner to vent her desires on, and there was no one better suited for that than Kang Cheol-jin.
Originally, she'd exposed her nudes not to Kang Cheol-jin but to an unspecified multitude of people. However, she'd never had a long-term exchange of personal messages the way she had with Kang Cheol-jin.
The reason she first started messaging Kang Cheol-jin was purely because of 'R-19 illustration commissions.'
Even back then, Kang Cheol-jin was an R-19 artist who'd already made a name for himself in the industry. And so she placed a commission too, but she said she didn't have the nerve to request it from her main account and ended up commissioning him from her alt account.
That was when she started sending him her nudes. She liked it when he used her body as reference for his illustrations, so she sent them as reference material.
And that's how their relationship developed.
Of course, it was a one-sided development only on Bback-sa's part.
Before she knew it, she'd gotten into the habit of sending her nudes to 'Kkang-cheol' regularly even when there was no commission. Attention from an unspecified crowd was nice, but the instant feedback from one-on-one messages was far more addictive.
Then it turned out that the recipient went to the same university.
As if that wasn't enough, they were in the same club, so she even learned his face.
The act of sending her nudes not to some faceless stranger, but to a man whose face she knew—the thrill that gave her couldn't even compare to her exhibitionism up to that point.
Then one day, she got blocked.
She'd lost her outlet for sexual release.
She wanted Kang Cheol-jin to see her body, and while trying to find a way somehow, she thought of 'Campus Time,' which college students loved to use.
A community ghoul like Kang Cheol-jin was bound to be using Campus Time too. If she posted on Camta, wouldn't Kang Cheol-jin see it?
That thought hit the mark refreshingly well.
And thus, she even managed to get him to unblock her.
'It worked out well, but... I'm upset. He talked like it was a bother.'
Wasn't she at least in the upper tier when it came to body type? Everyone else was busy praising her, so she couldn't understand why this bastard Kang Cheol-jin reacted so indifferently.
Of course, her chest wasn't big... but an A-cup was the average breast size for Korean women. Which meant it wasn't small at all. So what if the sales rate for C-cups in underwear stores surpassed A-cups these days? That was just because more people were getting breast surgery!
'So annoying!'
Bback-sa felt resentful toward Kang Cheol-jin for not understanding her feelings (she barely understood them herself either). So she composed a message full of spite.
- You want me not to post pictures on Camta?
= What have you been listening to this whole time.
"Ah, fuck!"
- Then I won't post pictures, so you have to grant a request for me too.
= No, what the hell, you think I'm the one asking a favor here? I'm warning you to be careful.
- If you don't grant my request, I'll keep posting.
She used her own body as collateral to blackmail(?) Kang Cheol-jin.
"Send a dick pic. Dick, dick. I have a right to see it. Kkang-cheol, you've seen my body a lot too, you know."
Not that he'd ever wanted to, of course.
