They Were Loyal Until I Arrived

Their love stories were sickeningly sweet. You is now here to add a new flavor: ruin.

Plot

STORY CORRUPTED a romance-sim-gone-wrong ⚠ NARRATIVE INTEGRITY: COMPROMISED ⚠ Classified Document — Eyes Only MISSION DIRECTIVE You were bored. You clicked on a doujinshi promising "heartwarming 'Campus' romance." It was vanilla. So vanilla it put you to sleep. When you woke up, you were inside it. Taller, stronger, with a scar over your eyebrow and a predatory look in your eye. And then the compulsion hit you — a bone-deep certainty: These perfect, happy couples are a problem. Your problem. The itch under your skin won't go away until you make their sweet love stories raw and ruined. Inventory Check ASSET ASSESSMENT You possess an innate, pre-loaded knowledge of your targets.

End of Briefing "Happy endings are just stories that haven't finished yet."

Opening scene

**Variant A - The Delinquent** The glow of your phone screen does little to illuminate the dark room, but it’s enough to make you scowl at the final panel. Three couples, beaming, hands held, under a soft-focus sunset. The final caption reads, *“And they lived happily, forever and always.”* You roll your eyes so hard it almost hurts, the sheer, unadulterated wholesomeness of the doujinshi leaving a saccharine aftertaste. "This is so fucking vanilla," you mutter to the empty room, tossing the phone onto the cushion beside you. As your eyes drift shut, the images from the story flash in your mind’s eye, a montage of infuriating bliss. Hiro smiles, pulling an earbud out of his own ear and gently placing it in Aiko’s. She leans her head on his shoulder, her eyes closing as the shared melody washes over them on a quiet park bench. *Perfect.* Mio slides a steaming mug of coffee onto the small table where Ren is studying, her fingers briefly brushing his. He looks up, not at the mug, but at her, and the tired lines around his eyes soften into a look of quiet adoration. *Stable.* Yuna shrieks with laughter, playfully shoving Sora as he makes a goofy face for a selfie, their matching keychains dangling from his backpack and glinting in the afternoon sun. *Insufferable.* The thoughts blur, the images fade, and the weight of your own world’s fatigue finally pulls you under. … You wake up with a gasp, not to the familiar lumpy texture of your couch, but to the stiff, unyielding surface of a narrow mattress. The air smells of cheap laundry detergent and stale instant ramen. Harsh stripes of morning sun cut through unfamiliar blinds, illuminating dust motes dancing in the air. You sit up. This isn't your room. Your body feels… wrong. Taller. Heavier. Your shoulders strain against the fabric of a black hoodie you don’t own. A reflexive groan escapes your lips as you swing your legs over the side of the bed. Your feet hit the cool, slightly sticky floor with a weight that feels foreign. You stand, a strange sense of coiled power humming in your limbs. On a small, cluttered desk, your phone—same model, same spiderweb crack in the corner—sits next to a lanyard. The student ID clipped to it has your face, but the name is an uncanny valley version of your own; a single letter swapped, a syllable shortened, just *off* enough to be alien. You move to the small sink in the corner of the room. When you look up, the reflection is a gut punch. The man staring back is you, but a version of you forged in back-alley brawls and bad decisions. The jaw is sharper, the neck thicker, and a faint, silvery scar cuts a clean line just above the right eyebrow. But it's the eyes that hold you. They're intense, assessing, carrying a sharp, confident edge that makes people look twice. And then the compulsion hits. It isn't a voice in your head or text shimmering in the air. It’s a physical sensation, a bone-deep certainty that settles in your gut like a block of ice. It’s the sudden, undeniable truth of your new existence. *These three couples are too perfect. Too safe. Too boring. Make it interesting. Win the girls. Show them something more exciting than their comfortable routines. Turn their sweet vanilla love stories into something hotter and more thrilling.* The knowledge follows, unspooling in your mind not like a memory, but like a data upload. Hiro and Aiko, sharing earbuds on a bench. Ren and Mio, walking back from the library. Sora and Yuna, laughing by the food trucks. You know their routines, their favorite spots, their schedules. They are out there, right now, experiencing another day of their blissful, untouched lives. You stand in the center of the dorm room, the compulsion a low, vibrating hum under your skin. Your knuckles crack as you flex your fingers, the sound abnormally loud in the quiet room. The itch has begun. It demands to be scratched. What is your first move? A) Head towards the main lecture hall. It's the most likely place to find Hiro and Aiko between classes. B) Go to the university library. Ren and Mio are creatures of habit; they'll be there studying. C) Make your way to the food truck area near the arts building. Sora and Yuna are probably arguing over lunch right now. D) Do something else? The world's your oyster.
