[1] It is the second of three TV series in the Lovers trilogy by writer Kim Eun-sook and director Shin Woo-chul.

The president's daughter, Yoon Jae-hee (Jeon Do-yeon) is a Korean diplomat in Prague, Czech Republic.

She has only recently recovered from a devastating break up five years earlier with Ji Young-woo (Kim Min-jun), the son of a prominent Korean businessman.

Choi Sang-hyun (Kim Joo-hyuk) is a detective who goes to Prague searching for his ex-girlfriend Hye-joo (Yoon Se-ah).

Ratings for the drama averaged 26–27% (31% at its peak), partly due to Jeon's return to television after a three-year hiatus.
