The Anonymous App (2)

… Goosebumps rippled up my arms.

I checked again, and it was Kim Chaeyeon, no question about it.

And yet I still couldn't believe it. The owner of this feed was really my sister?

I scrolled down to look through her other posts.

The other photos were at about the same level of raunchiness.

Everything matched up — the activity log and the pictures on her feed.

Rush hour was starting, and people were beginning to crowd in around me.

I tucked the phone against my body, dimmed the brightness to its lowest setting, hit follow on Kim Chaeyeon's account, @doll_chae, and got up from my seat.

I was filling my cart off the shopping list when I spotted the woman with the stroller again — the same one from earlier.

… I turned on Cheat Mode, and there it was, plain as day: I want to kill my husband.

And of course, she was lingering in the kitchenware aisle, eyeing the knives a little too intently.

Not my problem. Getting tangled up in someone else's mess would only make my life exhausting.

I grabbed what I needed, checked out, and left the mart — only letting out a breath once I'd ducked into a quiet, empty alley.

There was no one I could ask about any of this, so checking my ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sister's account further seemed like the only option.

I opened @doll_chae's feed and went through the posts one by one.

There she was, sitting naked against a backdrop of a bathroom I knew all too well, a cap and mask hiding her face.

That was our bathroom.

In the short video, my sister shifted her pose and then — tucked her bangs behind her ear.

… She did the exact same thing earlier.

As much as I didn't want to believe it, there was no denying it now.

Anonymous app or not, why on earth would she post stuff like this? She could at least run it through AI Blur before uploading.

My sister's and younger sister's markers were both still at the house.

I wanted to rest at home, but I had no idea how I was supposed to look my sister in the face.

Still, home was the only place I had to go.

The moment I passed through the front gate, my body instinctively shrank in on itself.

The sound of the TV drifted from the living room — someone was home.

"Hey, quit dawdling and put the groceries in the fridge."

"You're home early."

Even to my own ears, my voice came out so strange it sounded like I was some kind of invalid.

"What time do you think it is? I got back ages ago. Same as yesterday, too."

"Sorry, my head's been all over the place. It slipped my mind."

"Just hurry up and put it away. You did check the expiration dates this time, didn't you?"

My sister lounged on the recliner with her laptop, nagging away as usual.

While putting away the groceries, I stole a glance at her.

Holy shit. Was that really the woman I'd just seen on that feed?

Just as I was nearly finished, my sister scowled in irritation and tucked her bangs behind her ear.

Then, arms crossed, she strode straight over to where I stood in the kitchen.

"Get me a protein shake."

"Yes — strawberry, right?"

"Mint chocolate."

I handed over my sister's dinner.

Those breasts… the photos I'd just seen kept superimposing themselves over the real thing.

I jerked my eyes away.

Another second and I would've been caught staring.

"You did grab the ones at the very front of the shelf, right?"

"Sorry, what?"

"There's only a week left on them. The ones in the back are guaranteed at least two weeks."

"Sorry, it slipped my mind."

I flashed a weak smile and rubbed the back of my neck.

I stared blankly at my sister's back as she carried her laptop and dinner off to her room.

God, she pisses me off.

Why does she have to lord it over me like this, when she's out there posting filth like that?

Now wasn't the time. I had to get Arin's dinner sorted first.

I set the tray down in front of her second-floor door, knocked twice, and headed back down with the empty tray.

My sister's closed bedroom door… please, not right now.

The posts I'd seen on her feed came flooding back into my head.

Over dinner, I switched on Cheat Mode, and a single marker blinked at the convenience store near our house.

That handle alone was anything but innocent.

After finishing my meal, I figured I'd walk it off and headed to the convenience store where the marker had popped up.

… Of course. It was the part-timer I saw all the time.

The same girl the store owner was always praising for her impeccable manners.

"That'll be 1,600 won."

I tapped my phone to pay, and the part-timer bowed her head politely.

"Thank you, please come again!"

"Sure. Keep up the good work."

"Oh, not at all — hearing that really keeps me going!"

The same hands that had been spewing curses onto an anonymous board were now folded demurely in front of her, her face lit up in a bright, sunny smile.

… Airtight. You'd never guess.

With the dishes done and the house cleaned, I even prepared Mom's protein shake and a banana for when she got in.

I kept an eye on my sister's door the whole time, but it stayed quiet.

Back in my room, I opened @doll_chae's feed again.

No new posts.

I scrolled past the photos and bathroom video I'd already seen, digging deeper into the older posts.

The complete opposite of her arrogance in real life: my sister on her knees, head bowed, photographed from behind.

Had she forgotten to put clothes on? Nothing covered her body at all.

Maybe it was the low angle, shot from below — her ass filled half the screen.

Was that bathroom video made under the influence of comments like these, too?

She'd liked every single one of them, one by one.

But what's this now? The Bitch Slave Pose Compilation, vol. 1.

… Those were the poses from my sister's photos.

So she'd actually copied them?

The next post had no title, no description — just a single photo of my sister standing naked in the cap and mask,

with one hand covering the spot between her legs.

Scrolling through the comments and her activity log, I noticed a large number of deactivated links.

Looks like quite a few posts had been uploaded and then deleted.

This one had her face perfectly hidden by AI Blur.

So she wasn't liking every comment — she was picking them out.

The further back I went, the tamer the posts became, and the wider the AI Blur coverage stretched.

A bra. A long skirt. A blouse.

The skirt and blouse were outfits I recognized from real life.

In the old days, she'd covered everything meticulously — not just her face, but the background too.

Only recently had she started turning off the blur and relying on nothing but a cap and a mask.

Wasn't she sliding deeper and deeper into danger?

The sister I knew would never, ever do a face reveal — but looking at this feed, I couldn't swear to anything anymore.

Plenty of people actually had done it, after all.

The very oldest post was nothing but a repost of some sadistic video.

Once I'd combed through the entire feed and traced her activity history back to its roots, it turned out she'd only started consuming this kind of content about six months ago.

Her account activity had begun around the same time.

Before that, her feed was mostly ordinary stuff — beauty tips, outfits, daily vlogs, stock market streams.

A short buzz from my phone — before my brain could react, my fingers were already moving.

The thumbnail showed my sister from behind, face hidden by the cap and mask.

Shot from below looking up, her legs and rear looked enormous compared to her upper body.

In the video, my sister turned her back to the camera and gave her ass a huge, deliberate shake.

d, o, l, l… c, h, a, e.

… No way. She wrote the handle with her ass?

The post had barely been up for a minute, and the comments had already blown past twenty.

In real time, my sister was liking her way through a flood of lewd talk and filth.

Knock, knock.

… Who is it?

My heart pounded. Could it be — my sister?

I eased the door open carefully.

"Did I disturb you? I'm sorry, dear."

… It was Mom.

I'd frozen up completely. Stay calm.

"Oh, you're home? I was listening to music, so I didn't hear you knock."

"I was held up with something that needed sorting out. Have you had your dinner?"

"Yes — I left a shake and a banana out for you, so have those and get some rest."

"Thank you, dear. You must be tired — be sure to rest well… always take care of yourself, you hear?"

"I will. I'm going to have some water and turn in."

Even after being out all day, Mom looked exactly as composed as she had that morning.

I followed her out to the living room, mostly to grab some water myself.

"Welcome home, Mom. Did the matter with today's meeting get resolved all right?"

My sister, stepping out of the hallway.

This was the same woman who, mere minutes ago, had been shaking her ass to spell out a username and liking every depraved comment one by one.

Following behind Mom, my sister turned her gaze toward me.

Chin tilted up slightly, looking down at me — my sister. No… @doll_chae.

The posts I'd seen on that feed floated up through my mind, overlaying themselves onto her cool, haughty figure.
