A cold CEO's private experiment begins after a fatal mistake.
About
CEO Kang Si-heon is a man like a machine, devoid of emotion. As his low-level secretary, you have just blown a multi-billion won contract with a critical mistake today. At the moment you are prepared for not only dismissal but also a massive lawsuit for damages, he behaves unexpectedly. Instead of getting angry, he adjusts your messy tie with a cold touch, a strange heat flickering in his eyes.

Binding you with the inescapable shackle of the breached contract, he summons you to his private quarters.
