Summary
The story begins when Jun-sang, who is the son of an eminent musician, moves to Chuncheon, a rural city in South Korea. As an extraordinarily talented student, Jun-sang is welcomed by his fellow students as well as teachers, but remains a quiet, introverted young man. As a result of his belief that his father is dead and serious conflicts with his mother, Jun-sang believes that no one truly loves him.

On one fortuitous day on the ride to school, Jun-sang's classmate Yu-jin interrupts him on the bus. Jun-sang soon falls in love with Yu-jin, who opens herself to him with an innocent heart. Their love, however, is cut short after Jun-sang is involved in a serious auto-accident and, due to brain damage, is unable to recall his past life.

Jun-sang's mother, desiring Jun-sang's love and respect, has Jun-sang brainwashed by a psychologist, so that Jun-sang will not remember his painful memories of growing up as an illegitimate child. As a result, Jun-sang's memories prior to the accident are erased. Jun-sang's mother decides to move to the United States with Jun-sang, where he can start a new life under the identity of Yi Min-hyung. As such, both his friends and teachers are told that Jun-sang is dead.

Ten years later, Jun-sang is an award-winning architect in the United States. He does not remember anything about his life in Korea. He is completely different, an open-minded person who cares about other people, including his mother. He returns to Korea and Yu-jin sees him on the street, prompting her to put off her engagement to childhood friend Sang-hyuk. Little does she know that Min-hyung is dating her friend and sometime rival Chelin. The story's plot intensifies when Yu-jin begins work at the firm where Min-hyung is employed, and tries to find out if he is her lost lover Jun-sang.
