Drowning in her late mother’s debt and her father’s gambling habits, So-ui accepts a "lifeline" from the wealthy Kwon Chi-hyeok: pose as his fake fiancée to appease his ailing grandfather. It’s a predatory arrangement disguised as a sanctuary. Chi-hyeok plays the doting lover with terrifying precision, showering her with a calculated tenderness that So-ui—starved for affection—mistakes for genuine love. While he secretly mocks her "cheap" simplicity and treats her as a disposable outlet for his darker impulses, So-ui surrenders her heart and body to a man who views her only as a convenient toy.
The power dynamic shifts violently when the mask finally slips. Instead of breaking, So-ui reclaims her dignity by throwing Chi-hyeok’s own cold rationality back in his face, dismissing their shared intimacy as a mere "comfortable transaction" before walking away. This icy rejection shatters Chi-hyeok’s composure, transforming his cynical mockery into a dark, possessive rage. The fake engagement may be over, but So-ui’s defiance has ignited a real—and far more dangerous—obsession.
