Lin Xia had always believed exhaustion was just another word for dedication.
She had told herself that for years. Every late night, every skipped meal, every weekend sacrificed to the altar of Gu Corporation's endless deadlines was proof she was climbing. Proof she mattered. At twenty-eight she still lived in a shoebox apartment on the edge of the city, still ate instant noodles three nights a week, still answered "yes, sir" even when her boss screamed through the phone at 2 a.m.
That Tuesday night the spreadsheet refused to balance. Columns of numbers mocked her. Her eyes burned; her fingers trembled on the mouse. The last message from Director Li glowed on her screen:
"Fix this before morning or don't bother coming in."
She rubbed her temples, whispered "just one more adjustment," and felt something inside her chest give way—like a frayed thread finally snapping.
The world tilted.
Her forehead met the keyboard with a dull thud.
Darkness swallowed her.
When awareness returned, it came wrapped in sterile blue light.
A translucent panel hovered inches from her face, crisp and impossible.
[Welcome, Host Lin Xia.
Soul binding to [Perfect Mary Sue & Good Pregnancy System] complete.
Current mission world: Modern – "The President's Unwanted Substitute Bride"
Original occupant: Su Wan, 24-year-old secretary, Gu Corporation.

72 hours from now would be the time she commit suicide via rooftop jump
Lin Xia blinked slowly. Her body felt… different. Lighter. Warmer. The thin mattress beneath her no longer dug into her spine the way it used to.
She sat up.
The apartment was the same cramped studio—peeling wallpaper, single flickering bulb, the faint smell of damp and cheap ramen—but her hands looked unfamiliar. Nails manicured. Skin smoother. Even her breathing felt steadier.
"Is this a dream?" she murmured.
[Ding! Negative. Transmigration confirmed. You have replaced the original Su Wan.

Lin Xia pressed her palms to her face. Real. Warm. Alive.
Before she could form another question, a sharp, electric wave surged from her core outward—painful for three heartbeats, then replaced by liquid warmth.

The transformation settled like a second skin. Lin Xia rose on unsteady legs and crossed to the cracked bathroom mirror.
She stopped breathing for a moment.
The woman in the reflection was unrecognizable—and terrifyingly perfect.
Gone were the dark circles, the sallow complexion, the hunched shoulders of someone who had forgotten how to stand tall. In their place stood a creature built for worship: devastating symmetry, skin that seemed lit from within, eyes that promised both comfort and ruin. Even in the faded oversized T-shirt and shorts she wore to bed, the body beneath screamed temptation.
She touched her cheek. The reflection mirrored the motion perfectly.
"…This can't be me."
[Ding! Affirmative. This is now you.
First mission issued:
Survive tonight's banquet trap.

Her phone buzzed violently on the nightstand.
WeChat from "Yueyue ♡":
[Yueyue: Xiaxia~ Don't forget tonight!! Imperial Hotel, Gu Corp annual banquet. You still have the little packet I gave you last week, right? Just drop it in President Gu's drink when he's distracted. One sip and he'll be helpless~ Succeed and I'll make sure HR pushes your name for that senior secretary spot. You deserve it after all your hard work! Love you forever 💕]
Lin Xia stared at the message until the screen dimmed.
Original Su Wan had trusted this woman. Had believed the promotion promises. Had followed every instruction like a lamb to slaughter.
Lin Xia felt something cold and sharp uncoil in her chest.
She opened the wardrobe. Worn blouses, sensible skirts, one pair of scuffed black pumps. Nothing that matched the body she now inhabited.
The system chimed again, almost cheerfully.
[Ding! Starter gift pack deployed.

She dressed methodically.
The gown poured over her curves like liquid night—backless, the fabric clinging to every line, the slit flashing pale skin with each movement. The heels lifted her posture, forced an elegant sway into her walk. Makeup took half a minute: sharp winged liner, crimson lips, highlighter that made her cheekbones gleam like polished marble.
She fastened a simple silver chain around her neck—the only piece of jewelry Su Wan had owned—and tucked the drug packet into her small black clutch.
One last look in the mirror.
She no longer looked like a desperate secretary.
She looked like destiny wrapped in velvet.
[Ding! Current charm value: 99.9/100 (soft cap until further upgrades).
You are presently the most captivating woman within 100 km.]
Outside, rain hissed against the windows. Lin Xia stepped into the humid night, raised her hand, and a taxi pulled up almost immediately—as though the city itself had been waiting.
"Imperial Hotel," she said softly.
The driver glanced in the rearview mirror and nearly swerved.
"Yes, miss. Right away."
As the city lights blurred past the window, Lin Xia allowed herself one slow, private smile.
Tonight, the script would burn.
And she would be the one holding the match.
