Before Sea Shirase was hailed as the "White Rose Lady." On the day of the entrance ceremony at St. Liliana Academy High School, she was exceptionally eye-catching. Her silver hair swayed in the spring breeze, and her figure in the black uniform was like a painting. The surrounding students gasped at her perfect aesthetic beauty. Just by standing there, the atmosphere of the place changed.

Three months later, Sea's reputation grew daily. Her grades were always at the top of the class. In PE, she easily outran the aces of the sports clubs. In etiquette class, even the teachers were impressed. Everyone acknowledged it: she was a perfect human, an unreachable existence. Truly the "White Rose Lady," the "Pride of the Academy."

—And that is exactly why the impulse struck.

Guest was in a dorm room, staring at a smartphone screen. The depths of the dark web. The scrolling fingertip trembled. Displayed were suspicious strings of text and an eerie icon.

"Fattening App"

The review section was a scene of chaos. "I really got fat," "It's scary that it's irreversible," "I used this to make my wife fat... the sense of guilt is incredible," "I turned my annoying boss into a fat pig lol," "You can only use it once, so really think before you do."—Posts that could be lies or truth were lined up. The price was free. The download button blinked as if pulsating.

What flashed through Guest's mind was Sea's profile as she sat in the classroom with a cool face. That perfect contour. Those thin shoulders. The moment Guest imagined those things collapsing hideously—a finger touched the screen.

2:00 AM. The dorm's lights-out time had long passed. The sound of footsteps in the hallway had ceased, and the entire building was wrapped in silence as Guest sat up in bed, clutching the smartphone.

On the screen was a cold notification: "Installation Complete." The download took only three seconds. For all the grand hype, it was anticlimactically simple.

The problem started here. The app icon was a black heart wrapped in chains, and tapping it displayed the instructions.

"Simply point the camera at the subject and press the shutter. One-time use only. Effect is immediate. Weight, body fat percentage, and body type will change irreversibly. Cannot be canceled."

Guest's hands holding the phone were sweaty. The dorm at night was strangely quiet, and the faint sound of Sea's breathing could be heard from the next bed. Regular, peaceful breaths. The fact that the perfectionist Sea was sleeping so soundly was proof she had exhausted herself during the day's practice.

Sea turned over in bed. Her silver hair, peeking out from the thin blanket, glowed dimly in the moonlight. Her sleeping face was defenseless, looking like an ordinary girl her age, a far cry from her usual dignified expression.

Guest's thumb slid toward the camera app.

—And then, morning came.

St. Liliana Academy, 7:00 AM. The wake-up chime echoed from the speakers installed in each dorm room. The morning sun leaked through the white curtains, and the chirping of birds could be heard from the forest. And then... a snoring sound like a grunting pig roared out.
