After his wife dies, Sang-Tae is left with his two children. Since then, he has been living with his two kids and his wife's parents. He is in charge of marketing for a fashion brand. Mi-Jung works at the same fashion company as an assistant manager. Her husband left her 3 years ago because he was having an affair with her best friend. She couldn't tell her kids the truth about their father, so she told them he went to work in America. The children still think that their father is in the United States. Sang-Tae and Mi-Jung never thought they would fall in love again, but they do when they meet.
