The story begins with a car accident involving a man named Jung Joon-seok and it flashes back some scenes of him chasing a young adorable girl, his daughter Jung Hae-won, around the hanging blankets. He was living with his wife, Park Young-ran, Hae-won's mother.

Joon-seok's father, Jung Geun-woo paid off Young-ran to stop looking for Joon-seok and lied that Joon-seok doesn't want to see them. Young-ran tried to catch up to Geun-woo to return the money but failed resulting to her sudden faint because of her illness. The two kitchen helpers, Im Cheong-ok and Song Kyung-hwa, run to rescue Young-ran and while Cheong-ok was pulling Young-ran inside, Kyung-hwa happen to see the envelope which was given by Geun-woo and was shocked to see the amount of money inside.

One night, Cheong-ok was being pursued by some loan sharks and threatened her that they will kill her in front of her sons. She didn't have a choice but to steal the money from Young-ran but was caught red-handed. Young-ran beg her to return because she will return it but due to this, her illness become worst resulting to death. The scene was witnessed by Kyung-Hwa.

Kyung-Hwa made Cheong-ok her accomplice to divide the money and get rid of Hae-won. Cheong-ok refused but Kyung-Hwa threatened her about her killing Hae-won's mother. Kyung-Hwa begs Cheong-ok to do it since it will be for their sons and daughters who are in need to be raise well. Choi Soo-ji, Kyung-Hwa's daughter, overheard about their plan. Soon, Cheong-ok left Hae-won, while carrying a bear given by her father, to a train travelling to Seoul and watches her crying and calling her name. Back to Young-ran's home, Kyung-hwa was busy collecting Young-ran's jewelries. She didn't bother to notice that Soo-ji hid Hae-won's family picture to herself.

15 years later, the now 19-year-old Hae-won, Han Yoo-min lives alone with her adoptive brother, Han Kang-pyo. She has no memory of her childhood and only remembers herself running around the hanging blankets. One day, she meets Kang Min-jae, a doctor who treats her brother, and instantly falls in love. It suddenly turns out that Min-jae is Cheong-ok's eldest son. At the same hospital, Geun-woo was rushed inside and gave words to Joon-seok, who lost his memories after the car accident, to find her daughter 'Hae-won'.

Min-jae wanted to dedicate the wife position to Seo-yeon, the girl who left him without a word a year ago. But because of her mother who keeps pushing him to marry a tycoon's daughter, Min-jae needs Yoo-min help to pretend his fiancée until Seo-yeon return. Yoo-min, who lied to being a 22-year-old woman, decided to tell Min-jae her true age. Min-jae somehows accept her and they renew the contract of if Min-jae will fall in love to Yoo-min before Seo-yeon returns, their engagement will turn to real.

Soon, Yoo-min and Kang-pyo move into Min-jae's house as well as Soo-ji and Kyung-hwa. Soo-ji started to become suspicious of Yoo-min's identity after seeing her teddy bear, which is that she also has the same that is also given by Yoo-min's biological father.
