Smile is about a wealthy family who becomes penniless overnight and has to seek refuge at the house of their chauffeur who had served them for many years. Lee Min Jung plays the second daughter of the wealthy family and is someone who is self-centered and insensible.
Jung Kyung-ho will be the main love interest.
In the story, Lee Min-jung is the daughter in a rich chaebol household, while Lee Chun-hee is her immature older brother.
The SBS drama is Lee’s first leading role, and features her in a riches-to-rags role; her sassy, rash character is dumped by fiance Lee Kyu-han after her rich family meets with ruin. It’s only after her wedding ceremony with the son of an auto company president that everyone learns of her father’s company collapsing, and the fiance’s parents urge him to break it off.
When her family meets with financial ruin, she’s dumped by her former fiancé (Lee Kyu-han) until he decides he wants her back. Meanwhile, she and her family move in with their former chauffeur, played by Gourmet’s veteran chef Choi Bool-am. The ex-chauffeur now runs an auto center with his son (Chun Ho-jin of Job Well Done), who is married to Song Ok-sook (Beethoven Virus’s nervous cellist).
The two families struggle to adjust to living together, making for lots of bickering but also warm family moments and laughs.
Lee Chun Hee plays the son of a wealthy family who has just finished up his overseas schooling and has returned to Korea. The immature son wishes to marry his foreigner girlfriend and his family is less than pleased. He is Lee Min Jung's older brother.
