This drama is beautiful. One of the fine makjang Kdramas from the 2000s: almost every cliches are in it. I cannot write them here or I will spoil the story. You better watch it yourself. My guess that the rating is low due to it was made in 2006 and the viewers who rated it came from era after this site is established (2011), where Kdramas have shifted to supernatural, Kidols, or time travel theme. This drama gave me heart palpitation. For sometime I could not finish Episode 1 due to the intensity and angst. I feared the female character Eun Seol's life!

What I like about this drama:
(+) The story is not boring. Although the main scheme is revealed in the middle of the drama, there are other plots to come. Even until a few last episodes. You won't get bored.
(+) Emphasize of the importance of family
(+) This melodrama is also balanced with light-humor scenes of the housekeeper and daughter relationship and the sycophant office assistant
(+) Chilling Shin Jun spying on Eun Seol scenes
(+) Touching love pledge and wedding scenes at the church
(+) Strong chemistry between Male Lead and Female especially since they meet very early in the first episode
(+) This is one of a few romance dramas that have older characters who played important roles with lots of screen times.
(+) Outstanding acting of actor Joo Jin Mo as the heartless and scheming Shin Jun brought by past pain and anger, turned to a romantically in love mad man.
(+) Amazing acting of actress Lee Bo Young as Eun Seol. She brought a smooth character growth from spoiled, snotty, but naive, doubtful heiress to hard-working, determined,impoverished, mature woman.
(+) Excellent acting of actress Na Young Hee as Shin Jun's alcoholic and psychotic mom
(+) Impressive acting of actor Han Jin Hee as Eun Seol's overprotecting dad and conniving businessman
(+) Great acting of supporting characters as individuals as well as relationship with other characters (I can say good non-romantic chemistry)
(+) Costume is relatable to modern day fashion. Not many clothing are outdated considering this drama is made in 2006
(+) Beautiful film location in New Zealand

What I don't like about this drama:
(-) Some dragging scenes and conversations, probably typical older Kdramas.
(-) A few unrealistic scenes, for example: Eun Seol length of pregnancy. She was still pregnant (not showing sign) although Shin Jun was released from the prison one year later.
(-) TOO many dialogues with 'what to do' sentences.
(-) Not sure why they have to 'redeem' Shin Jun thru amnesia. IMO it is better without amnesia incident, as Shin Jun will have either revenge or forgive Eun Seol
(-) Too many slapping scenes, especially slapping poor Eun Seol
(-) Excessive application of lip gloss for female characters. Even they put lip gloss on Eun Seol's deceased mother portrait!
