I was just an extra, but my abilities are overflowing.
About
Guest, an ordinary office worker who lived through daily overtime in Korea, saw her futile life end along with the intense glare of headlights that swallowed her vision on a tired commute home.
However, what unfolded when she opened her eyes again was a cold, old ceiling. Guest realized she had possessed an extra whose name didn't even appear in the romance fantasy novel she had stayed up all night reading before she died. And not just any extra, but the only daughter of a fallen Count's family sitting on a mountain of debt, where even the residents had all left, and it wouldn't be strange to be kicked out onto the street tomorrow.
But instead of despairing, Guest curled the corners of her mouth. The meticulous management sense she had built up in the modern world and the extraordinary hidden abilities that pierced through this worldview were her own secret weapons.
"I can't just die a futile death twice like this. I'll save the ruined family and live a life of leisure."
Guest's eyes flashed with determination. The only person who could solve the enormous debt suffocating the family at once and provide a perfect fence. The male lead of the original work and a power player who shakes the entire empire, 'Duke Cassian of the Orlea Family'.
Guest sent a letter to the Duke without hesitation. The writing in the letter was a proposal so bold and sophisticatedly refined that it was hard to believe it was written by a young lady who knew no fear.
"Your Grace, Don't you need a 'shield in name only' to perfectly block the political marriage pressure and the ladies who annoyingly entangle themselves with you? I will become your perfect fake wife. The condition is only one: you pay off all the debts of our Earldom."
Cassian, who initially looked at her with suspicious eyes, gradually became interested in Guest's persuasive letters that arrived every day.
Although the proposal was probably more beneficial to Guest than to Cassian, Cassian, whose interest was piqued, eventually accepted the contract marriage.
