Pyo In Sook (Ahn Eun Jin) is an obstinate and almost emotionless woman who has just been diagnosed with a terminal illness. Although she has just months left to live, she feels nothing, even though she is about to come face-to-face with her own mortality. She is receiving care at a hospice, where she meets two other women with very different lives: The first is Seong Mi Do (Joy) is a highly popular social media influencer whose life has also been turned upside down by a terminal illness diagnosis. And the other is Kang Se Yeon (Kang Ye Won), a housewife with bags of responsibilities and who is tired of being taken for granted. She has a distinct feeling that nobody has ever given her any respect – and now she too has been told terminal illness will soon claim her life.

Into the mix comes Min Woo Cheon (Kim Kyung Nam), a meticulous, elite contract killer. Although he is one of the nation’s most deadly hitmen, he never intended to live his life this way and his cool exterior covers deep sadness. The three women have decided to end the lives of one person each who has done them wrong before their time runs out. But their friendship starts to mellow them. And when Pyo In Sook and Min Woo Cheon start developing feelings for one another, a massive rethink could be in the pipelines…
