Synopsis
When her pregnant friend gives birth then dies after a vehicular accident, Jung Da-so (Song Hye-kyo) raises the child as her own. Da-so was an orphan, so she endures the stigma of being an unwed mother in order for her daughter to have a family.
Ha Tae-woong (Kim Min-jong), who was raised by his uncle after his mother died, has never met his father. Da-so and Tae-woong meet as employees of Woori Company, whose president is Tae-woong's father. Through a twist of fate, their lives become entwined with Kang Sae-hyun (Yoon Da-hoon) and Ho Ji-soo (Kim Min), and Da-so sees both the best and worst in human nature.
