Getting 100 Million for Being Locked Up for a Year - Possible?

Synopsis

Late one evening, a large sum of money was transferred into her account. “Any questions about the transfer? Talk to the bank directly! That’s all I’m saying!” There was no way he could just give it back. It wasn’t that he wanted to pocket someone else’s money—that’s just how the world works these days. Did you think I’d fall for voice phishing? But the moment the shadowy group stormed into her home, Song-Yul realized something was terribly wrong. One man stood out distinctly from the rest. Model-like tall stature and striking features. Even his loosely worn suit seemed charming, such was the intensity of his presence. He delivered his demand to her in a cold voice. “One hundred million.” “Yes? Yes?” “I’ll give you 100 million won if you stay locked up like a corpse for a year.” A year of confinement for 100 million won? It’s far more dangerous than expected, and far sweeter.
