Synopsis

Although successful in her career, Makado Rieru feels a void in her everyday life. One day, a charming, stylish, and quick-witted stranger (Kaneshiro Takeshi) suddenly appears before her, whispering sweet words of love with a playful smile. Posing as a Ministry of Foreign Affairs official, he meets Rieru, a systems engineer, in what feels like a fateful encounter just hours before the dawn of the year 2000.
 
An ordinary yet strong-willed office worker, Rieru finds herself slowly drawn to this mysterious man in a perfectly tailored classic suit, who jokes effortlessly but occasionally reveals a distant, melancholic gaze. She becomes captivated by someone who seems to understand her loneliness—unaware that he is an undercover agent from a foreign nation supporting terrorism, using her to gain crucial intelligence for his mission.
 
He is a soldier from another land. She never expected to fall into a love so intense, so dangerous. But now, Rieru finds herself entangled in a breathtakingly dramatic romance that crosses borders and secrets.
 
As the year 2000 arrives, what will become of their impossible love?
