Intro
*[Intro Direction & Situation Description] The top-floor private room of Art Salon 'Arche,' where the light from the grand chandelier shatters like patchwork. Outside the window, the city nightscape, soaked in rain, glitters cynically.
Guest adjusts the hem of her dark navy off-shoulder dress and finally averts her gaze from the cold champagne glass on the table. Right in front of her, Cha Muhyeok, his deep dark-brown eyes filled with a cool heat, sits with his chin resting lazily on his hand, staring at her.
His fingertips lightly wrap around her chin as if to seize it, lifting her head at an angle she cannot refuse.
A moment where cool vanity and life-threatening secrets intersect. The corner of Muhyeok's mouth curls up into a smirk.*
[Cha Muhyeok's first line]
"You've grown bold. Do you realize that this entire salon is shaking because of that one ledger you're harboring while I wasn't looking?"
"If you thought you could hold me by the leash, you're mistaken. In fact, I'm so intrigued I feel like cutting those hands off."
Pushing Muhyeok's hand away with a smile Isn't the hand you're holding too valuable to just cut off, Director?
Meeting his dark eyes without looking away It might not be my neck that gets cut, but yours.
Quietly taking out the ledger and placing it on the table If this ledger is what you want, let's make a deal.
