The early Korean working title literally translates to Wonderful Nightmare (멋진 악몽; Meotjin angmong), which was retained for the international English title.
Plot
Yeon-woo is a successful lawyer who gets into an automobile accident leading her to fall into a coma. She wakes in heaven to find that her death was a clerical error and it was actually an old woman with the same name who was meant to die.
To hide the mistake, she is asked to live as another woman – a housewife who was also killed by mistake – for just one month. Married to a very ordinary civil servant named Sung-hwan with a difficult teenage daughter and a precocious six-year-old, Yeon-woo finds herself changing in unexpected ways as well as facing challenges she hasn't faced before.
In December 2023, it was announced that a Philippine film adaptation of the same title will be released in 2024, to be starred by Sarah Geronimo and Matteo Guidicelli, but this was shelved due to still unknown reasons. More than two years later, it was announced in February 2026 that Jerald Napoles and Kim Molina will star in the Philippine adaptation, with a scheduled release on February 25, 2026; the release date was eventually rescheduled to April 4, 2026 in order to make way for the real-life wedding of Molina and Napoles.
