Synopsis

A human suspense drama that explores the struggle between guilt and friendship, and the courage it takes to confront a mistake that can never be undone.
 
The series follows Nakata Yume and Oosako Mio — two women brought together by tragedy. Two months prior, Yume believed she had saved a woman on the verge of ending her life, only for that same woman to fall from a building and die that very night. The deceased woman’s only daughter, Oosako Mio, is unable to accept her mother’s death as a suicide and is consumed by grief and despair.
Then one day, Yume and Mio cross paths by chance. The moment Yume realizes that Mio is the daughter of the woman who died, the full weight of her mistake comes crashing down on her, yet she cannot bring herself to tell the truth. Despite the secret standing between them, Mio slowly begins to open up to Yume, and the unlikely friendship that blossoms between the two continues to grow in ways neither of them could have expected.
