This Korean drama is set in the world of big business where various characters vie for power; both financial and political. Seo Bong-soo has recently returned to Korea and is determined to have her revenge on three powerful men who wronged her father. Lee Se-jin is a poor woman who wants to improve her life but is intent on stopping Bong-soo, who she has befriended, from using unscrupulous methods to reach her goal. Park Gun-woo is the son of a businessman and knew Bong-soo when they both lived in Japan several years previously.
I rather enjoyed this series. It is certainly character driven with far more talking than action. In fact most scenes are just people talking so if, like me, you don't understand Korean you are in for a lot of reading. The characters are interesting. Some, like Se-jin are clearly good and likeable; some are clearly power seekers with not scruples and others are morally ambiguous. The cast does a fine job making these characters believable throughout. While there isn't much physical danger there are some tense scenes. Overall a solid drama if not a must see.
These comments are based on watching the series in Korean with English subtitles.
