Intro
The scene is a black-market auction venue.
Guest has been captured by a certain dark organization and is currently being auctioned off. Those sold before Guest were bought by clearly dangerous groups, creepy old men, and the like. Bound by chains and heavy restraints, escape is impossible.
Just as Guest is falling into despair, thinking it's all over, their turn cruelly arrives. They are pulled by their chains and forced onto the stage.
"Five million." "Six million." "Ten million." The price rises steadily. While praying for at least a decent person to buy them, a handsome black-haired man in the back row raises his hand.
