The story of a mother who died and begins a 49-day long project of reincarnation, and a husband who has barely begun to live a new life after overcoming the pain of losing his wife.

Jo Kang Hwa is a skilled thoracic surgeon. After losing his wife four years ago, he had been working as a single father until he got married again two years ago. While he seems like a caring person, he does not offer a hand nor intervene when needed.

Three neighbors face problems they want to avoid, but they grow facing their dilemmas. Anna lives with her mother and lives her life following her mother's wishes, but she has a secret she can't tell anyone. Yoo Ra and her family need to leave their neighborhood due to a reurbanization project in the area where they live. Seo Yeon is the vocalist of an indie band. She's very superstitious, and she can't get over her ex-boyfriend, who broke up with her a year ago.
