Chapter 1

[Story based on what I like, which is:
Envy & revenge
Mean-girls vibe girl being forced to uncontrollably gain weight. In denial and despises her new self, until eventually she may accept this reluctantly, hopelessly, realizing she will never be able to go back
No gore / explicit description, main focus on character's WG and denial / envy
Will include forced feeding / restraints later
Will involve humiliation from others]

Mira used to count her worth in calories. Every number, on the scale, on the nutrition label, on her sister’s tongue, was a wound that never fully closed. Growing up, she had learned that laughter could be sharper than knives, and her sister Lina's laughter had always been the sharpest.

Her sister Lina was the kind of girl who seemed born to be seen. Slim, bright, effortlessly magnetic, charismatic, the sun in every room she entered. When they were kids, their mother used to dress them in matching clothes for family photos, but the camera always seemed to tilt toward Lina.

“Maybe if you smiled more,” Lina would tease. Or worse: “Maybe if you stopped eating like a pig.”

Mira remembered pretending it didn’t hurt. She would smile, joke back, even laugh sometimes, because it was easier than crying. But the mirror in her room never lied, and neither did the hollow ache of wanting to be seen and appreciated disappear.

Years later, the sisters found themselves under the same roof again. Mira was 27, still soft around the edges, her body steady at just under two hundred pounds. She worked long hours as a data analyst for a logistics firm. Her days were spreadsheets and code, and her evenings were reheated dinners eaten standing by the counter.

Lina had just moved back to the city after getting laid off as the start-up she worked in collapsed. She was 23, job-hunting half-heartedly, but in reality spending more time scrolling through Instagram than sending résumés.

Lina had that kind of slender grace that never looked effortful. Smooth hair that fell perfectly without trying, a waist that still fit into the same jeans from college, and skin that always caught the light just right. Even in old T-shirts, she looked like she belonged in a lifestyle ad. People turned when she walked past, still drawn to her the way they always had been. And she knew it. She had the same easy confidence, the same teasing tone that somehow hadn’t grown up with her.

They rented a two-bedroom apartment to save money. It wasn’t large, but it was what they could afford. Mira took the smaller room without arguing. She told herself it didn’t matter. She told herself that she was older now, that things had changed.

But they hadn’t.

“Do you still eat ice cream for dinner?” Lina laughed one night as Mira came home late, a takeout bag in hand.
“No,” Mira said flatly, hanging her coat.
“Good. You are kind of... chubby, remember?” Lina smirked. “Guess you finally figured it out.”

Mira said nothing. She just walked to her room, shut the door, and stared at her computer screen until the words stopped stinging.

If she had known what would appear there the next night, she might have looked longer.

But for now, she only exhaled, heavy and tired.

[I combined Chapter 1 & 2 because they aren't that long. Here's the original Chapter 2.]

The next day, morning came late through the thin curtains. Mira sat at the counter, stirring sugar into her coffee, half awake. She had a meeting at nine, and her laptop was already open beside a cooling slice of toast.

Lina breezed out of her room like a commercial break -- hair tied up perfectly messy, wearing She hummed something under her breath, the sound bright and careless.

“Morning,” Mira said.

Lina yawned and leaned against the counter. “Morning. You’re up early. Didn’t think you're a morning person unless there’s food involved.”

Mira looked up, half-smiling. “I have a meeting.”

“Oh, right. The data job. Must be nice, getting paid to sit.” Lina opened the fridge, rummaging until she found almond milk. “I seriously don’t know how you do it. I’d go crazy if I couldn’t move all day.”

She poured herself a glass, then turned, eyes flicking over Mira’s figure. “Actually… maybe that explains a lot.”

Mira’s spoon froze midair. “Excuse me?”

Lina gave a little laugh, the kind meant to sound harmless. “I’m just kidding, relax. You’re fine! ” She said. “We could do a detox together sometime. Might be fun.”

“I’m good,” Mira said quietly.

“Okay, okay, don’t bite my head off.” Lina took a dramatic sip of her almond milk. “I’m just trying to help. You get so defensive whenever I bring this up. It’s honestly kind of sad.”

Mira stared at the counter. She’d learned long ago that arguing didn’t help. Lina never fought fair. She smiled while cutting, laughed while twisting the knife.

Lina leaned on the counter, scrolling through her phone. “Anyway, I’m meeting Emily later. We’re trying this new brunch place. You should come... oh wait, right, you’re working.” She grinned, and the door closed with a careless click as she left.

Mira sat in the quiet that followed, the sound of her own heartbeat loud in her ears. She wasn’t sure if it was anger or shame that burned hotter. Maybe both.

By late evening, the glow of the monitor was the only light in the room. Outside, rain began to tap against the window.

Mira rubbed her eyes and leaned back, ready to shut everything down for the night, when the screen flickered.
Once, twice, then fully glitched into a strange game interface --

[User: Mira Carson]
Connected Subject Detected: Lina Carson
Adjustable Parameters Available:
Appetite — Metabolism — Body Shape — Cravings — Energy — Weight

Mira blinked, confused. It looked like a game interface, but with her sister’s name glowing at the top like a status bar. For a moment she thought she’d fallen asleep at her desk and was dreaming.

Then the cursor appeared beside a single line:
Modify: Appetite (0–10)

She hesitated, then, almost as a joke, clicked the increase arrow twice.
+2.0

The glow rippled once, then faded. Nothing happened. She laughed quietly at herself shut the laptop.

A few minutes later, her phone buzzed.

Lina: Hey, you didn’t eat all the leftovers, did you? I’m starving over here.
Another message followed before Mira could type back.
Lina: You really shouldn’t keep junk food around. Some of us actually have self-control.

Mira stared at the screen, a small, humorless smile tugging at her mouth. The way Lina’s messages read now -- sharp, superior, and completely unaware -- suddenly felt absurd. Her eyes drifted back to the faint blue glow on her laptop. The cursor pulsed softly beside her sister’s name, as if waiting.

Mira’s finger hovered over the arrow again. She didn’t laugh this time.
