Korean Drama9: Cinderella's Sister

Cinderella's sister is normally stereotyped as an evil and negative character, but in this Korean drama, Cinderella's sister is so much like a female victim who was somehow "sabotaged" by Cinderella (for her, she thinks she was a victim.)  Cinderella's always the one who is depicted as a pure and a positive person who eventually lives happily with her love. Yet, who knows, in fact, Cinderealla's sister is, at the same time, eager to be loved?
This drama overturns some ideas of what we think of Cinderella's sister and somehow, viewers will look pity on her after watching this drama.
The story basically talks about  Song Eun-jo, who lives with her mother since years ago (and also her mother's lover), finally gets a new family and a home when her mother remarries to a kind man who owns a winery. At first, she was living in struggle and even attempted to escape rather than dealing with the attempt of being schooled. The cynical Eun-jo is unable to accept the affection of her new step-sister Hyo-seon  and step father Gu Dae-seong . Hyo-seon, with her bright character, is the apple in her father's eyes and Eun-jo's mother goes out of her way to fulfill the role of Hyo-seon's mother, causing her to neglect and act harshly towards Eun-jo. Yet, Eun-jo finds a friend, who is a college student working at the winery who becomes her own prince. Ki-hoon eventually leaves to take care of personal issues, but Hyo-seon, this Cinderella's  jealousy toward Eun-jo causes Eun-jo believe that he has abandoned her. The three characters reunite 8 years later to begin the main plot - a modern adaptation of Cinderella with a twist. Han Jeong-woo , a boy that Eun-jo considered her little brother 8 years ago, shows up in order to be near her and fulfills the role of a "fairy godmother" to her. A love triangle forms when Hyo-seon falls for Ki-hoon, who is still in love with Eun-jo. The feeling of betrayal lasts with Eun-jo, creating misunderstandings and difficulties. Yet, the kindness of Eun-jo's stepfather (Gu Dae-seong, Hyo-seon's father) begins to change everyone's lives.
