Plot

A dangerous and affectionate romance between a man whose time stops after being killed by his beloved lover and a woman who loses her memory of her previous life and whose time passes away endlessly.

Han Joon-O (Kim Young-Dae) is a top star in Korea. He seems like a perfect person with a tall, handsome appearance, but he is saddled with an inferiority complex. He belongs to Beginning Entertainment, which his older brother Han Min-O (On Joo-Wan) runs. One day, Han Joon-O takes part in a public advertisement with firefighter Kang Young-Hwa (Pyo Ye-Jin). During the filming of the advertisement, a car accident occurs. Kang Young-Hwa is able to save Han Joon-O in the accident. After that, Kang Young-Hwa begins to work as Han Joon-O's body guard. Meanwhile, after the car crash and when Han Joon-O wakes up, his body is possessed by the vengeful spirit of Do Ha (Kim Young-Dae). Do-Ha was a nobleman in Silla and he was killed by his wife Han Ri-Ta (Pyo Ye-Jin), whom he loved deeply.—AsianWiki

Han Joon Oh (Kim Young Dae) is a leading South Korean celebrity. He is stunningly good-looking and tall, but is secretly plagued by an inferiority complex that leaves him permanently insecure. One day he is hired to appear in a public service video. But the shoot goes horribly wrong, and Han Joon Oh is involved in a potentially fatal car collision. He is only saved by the quick thinking of a female firefighter named Kang Young Hwa (Pyo Ye Jin), who pulls off a heroic rescue. Han Joon Oh's representatives hire Kang Young Hwa to work as the star's personal bodyguard, recognizing her incredible talents. But when Han Joon Oh awakes from his stupor in hospital, he has changed completely - as his body has now been possessed by the spirit of a nobleman from ancient Korea. This nobleman, named Do Ha, was killed by his beloved wife Han Ri Ta (also played by Pyo Ye Jin) - and the vengeful spirit is on a single-minded quest for retribution.—Rakuten Viki
