Confined for 1 Year for 100 Million Won, Deal?

Synopsis

A woman receives an unexpected fortune in her bank account and refuses to return it, convinced it’s a scam until a dangerous group breaks into her home. Their intimidating leader, striking in appearance and ice-cold in demeanor, gives her a chilling ultimatum: disappear for a year in exchange for a massive payout. What begins as forced confinement soon reveals itself to be far more perilous… and far more tempting.
