After graduating from high school, Jin Dal-rae begins working at a local bank in Pyeongchang County. There, she meets Jang Tae-oh, a mountain climber, and she follows him to Seoul, where they get married. Dal-rae becomes pregnant, but before the baby is born, Tae-oh is killed in a freak accident in the mountains. Dal-rae moves in with her mother-in-law, Lee Soon-seom, and together the two women raise her daughter, Yoo-jin.
Several years pass, and Soon-seom herself encourages Dal-rae to move on, even setting her up on blind dates. During one such date, Dal-rae meets the elderly and wealthy Chairman Kim, who isn't really looking for a young wife, but searching for a prospective spouse for his socially inept son Jin-goo. Chairman Kim is impressed with Dal-rae's kindness and integrity, and is determined that she become his daughter-in-law.
Meanwhile, Dal-rae also encounters Kwon Oh-joon. Oh-joon was once a boxer, but he quit because he didn't want to mess up his "pretty boy" face. Since then, he has been masquerading as a fund manager, but in reality he is a con artist who lives off lonely, gullible women by scamming them. His sister Oh-sook is married to an abusive husband, and Oh-joon has been paying off her debts, but he soon grows desperate with the loan sharks hounding him and threatening to kill him unless he pays up. Learning that Dal-rae has been saving to start her own business, she becomes his next target. But as he gets to know her and her family, Oh-joon finds himself falling in love for real.
