It's 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.
The series revolves around the narcissistic Lee Young Joon, the vice president of a company run by his family. He is very self-absorbed and thinks highly of himself, so much that he barely acknowledges the people around him. Lee Young Joon has a capable and patient secretary in Kim Mi So who has remained by his side and worked diligently for 9 years without any romantic involvement. However, Mi So now want to set her life & focus on herself so when she decides to resign from her job, hilarious misunderstandings ensue. After 9 years of their strictly-workplace relationship, can it now develop in something more?
