O Hayat Benim (English title: That Is My Life) is a Turkish television drama originally broadcast on FOX from 2014 to 2017.^[1] The series follows Bahar who was snatched from her mother's arms (Hasret) at birth by her grandfather and is put to live with his servants until, many years later, the old man reveals her existence to her millionaire birth father (Mehmet). As her birth father comes to collect his daughter, Bahar's adoptive mother (Nuran) uses her biological daughter Efsun in her stead to gain wealth for her poor family. Halfway throughout the series, the lie is revealed, but problems deepen between the characters residing in the Mehmet estate and those whose lives revolve around them.
