- Synopsis -
The story begins with toddler, Jun-Suh accidentally caused the switch as he dropped the namecards on the two babies cribs in the baby room . A nurse who came in put them back incorrectly. The story then continue with the teenage years of the two main characters: Yun Joon-suh (played by Choi Woo Hyuk) and Yun Eun-suh (played by Moon Geun Young). They are the children of a rich professor and believed they are biologically brother and sister until Eun-suh gets in an automobile accident. At the beginning, Eun-Suh is very popular in school whereas Shin-Ae is smart but does not get the attention she craves for from the teacher and their classmates. Later, their situations are reversed when the switch is discovered.
After blood tests were carried out by the doctor on Mr. and Mrs. Yun for Eun Suh's transfusion, the Yuns find out that Eun-suh belongs to a Mrs. Choi, and Choi Shin-ae (played by Lee Ae-Jeong), is the Yun's biological daughter. At first, only the parents of Shin-ae and Eun-suh knew about this, but eventually, Shin-ae discovered the truth after she got into a fierce argument with her non-biological mother over a teddy bear she received from her biological father. Eun-suh only discovered the truth after Shin-ae wants her biological parents to take her in. In the end, the two daughters were returned to their rightful parents. Eun-suh now lives with the Choi family, where her biological father is dead and her widowed mother operates a small restaurant living in abject poverty.
Years went by, and in the duration, the Yun family went to the United States, where Jun-suh (now played by Song Seung Heon) returns to South Korea as a successful artist. He went back to the town he lived in, where he encountered his old friend, Han Tae-seok (played by Won Bin). They both stay at the hotel where Eun-suh (now played by Song Hye Kyo) works as a telephone receptionist. Tae-seok (who doesn't know about the entire brother and sister mixup that happened earlier) fell in love with Eun-suh and played games with her until she was fired from her job. One day Eun-suh saw Joon-suh and followed him to the beach where he was with Yumi (his fiancee) and Tae-sok and the two "siblings" finally meet after ten years.
Both Eun-suh and Joon-suh pretended to have a sibling relationship in front of the others at first but Shin-ae (now played by Han Chae Young) - angry at Eun-suh for taking away Tae-sok - exposed the two after she found a love letter Eun-suh had written to Joon-suh.
As a fight between Jun-suh and Tae-seok grows over their professed love for Eun-suh, she discovers she has leukemia (the same illness that took her biological father's life). She didn't tell anyone until the disease was at a terminal stage. All hope was lost by now, and Eun-suh died as Jun-suh was carrying her around the beach where they spent her birthday as teenagers.
Before Eun-suh died, she told Jun-seo not to follow her in death, and to continue living. However, Jun-suh, dazed and grief-stricken by the death of his lover and "sister", was struck by a truck (ironically the story starts with Eun-suh being struck by a truck) and dies.** my first kdrama. it made me cry no matter how many times ive watch this **
