Spring Waltz

Yoon Jae-ha (Seo Do-young) is a wealthy young man who lives an honorable life as a gifted pianist. As a child, however, Jae-ha lived with his father who was a conman and endured a miserable childhood. Seo Eun-young (Han Hyo-joo) lived on the island of Chungsan with her mom happily. Darkness came when Lee Jong-tae (Lee Han-wi) and his son Soo-ho (Jae-ha's real name) appeared. The man stole money from Eun-young's mother, which was set aside for Eun-young's surgery. When Eun-young's mother travels to Seoul to look for Jong-tae, she dies in an accident. At the hospital where Eun-young is hospitalized, Jae-ha's foster mother Hyun Ji-sook (Geum Bo-ra) was also there due to her son's death. Her diplomat husband Yoon Myung-hoon (Jung Dong-hwan) asks Soo-ho to become their son, and they would in return pay for Eun-young's surgery. Soo-ho now adopts the identity of Yoon Jae-ha (the name of their deceased son) and leaves for Austria. Meanwhile, Eun-young successfully receives her surgery. She grows up with a new family, and now makes accessories and sells them on the streets. One day, Eun-young wins an exhibition contest and, as a prize, travels to Austria. There she meets Jae-ha and his friends Phillip (Daniel Henney) and Song Yi-na (Lee So-yeon). When Jae-ha and Eun-young first met, they were at odds, but slowly they began to feel attracted to each other. Jae-ha then makes the shocking discovery that Eun-young is the girl he met in the past. Jae-ha tries to hide this from Eun-Young, but she eventually finds out, and leaves. As Eun-young tries to forget Jae-ha, she returns to Korea and there, Jae-ha appears again.
