On the day she is diagnosed, she discovers flirtatious chat logs between the male lead and his former crush. Seeing how similar their faces are, she thinks she is a substitute. Heartbroken, she prepares to leave.

The male lead dies on Valentine's Day. His final gift to the female lead is, astonishingly, divorce papers that are nine months overdue.
