Synopsis
Yeon-hwa and Yoo-ra became sisters after Yeon-hwa's mother engaged with Yoo-ra's father, but there is an invisible distance between both of them, especially Yeon-hwa's lover is Yoon-jae, who Yoo-ra crushes on. Until one day, Yoo-ra's car accidentally crashes into Yoon-hee, Yoon-jae's beloved sister, causing her to die. Yoo-ra then, comes up with a plan to blame Yeon-hwa for the accident, with the help of her father; a judge, and a police officer Park, whom she and her father bribed. This causes Yeon-hwa to be sentenced in jail for three years. When Yeon-hwa heard the news that Yoon-jae and Yoo-ra are to be married, she manages to escape from jail and plans to show up at the wedding unannounced, and do something drastic to Yoo-ra to get her to confess. After knowing that Yoon-jae and Yoo-ra are now a seemingly happy couple, Yeon-hwa decides to focus on keeping her health strong, and gives birth to a boy named Tae-yang (she didn't know she was pregnant before trying to escape prison). Because she is in jail, she is only allowed to take care of her baby for 18 months, and the baby has to be sent away, where they can get picked up after their parent is released from jail. At 18 months, the baby is heading off to an orphanage. However, Yoo-ra finds out about the baby and decides to switch his identity with another baby and send Tae-yang to a different couple, who was looking for a kid to adopt.
Later on, Yeon-hwa is released out of jail earlier, and she decides to bring Tae-yang home, but she quickly finds out that Tae-yang is nowhere to be seen and that none of the kids found at the orphanage is her child. Devastated, she decides to go on a search for Tae-yang, as she starts to revenge on Yoo Ra, Choi In-seok, and police officer Park Chang-do, and prove her innocence. Her revenge goes through many hardships, though, as her mother is kidnapped 2 times and has become disabled and hospitalized. She also finds out about Tae-yang's death, which is fake written by Yoo-ra. But many times, Yeon-hwa succeeds in her plans, and wins over the position as vice president of J Cosmetics, and gains the trust from chairwoman Julia, Yoon-jae's biological mother, who was once set up by Yoon-jae's stepmother, causing Yoon-jae to misunderstand that his mother was cheating when she really was set up. Yeon-hwa, also starts a relationship with the president of J Cosmetics, Choi Kang-wook, who is also the stepbrother of Yoon-jae.
