At twenty-seven, Su Yu finds a notebook at her father's funeral, filled with seventy moments from her childhood and youth. When the "Echoes of Yesterday" System activates, she gains seventy chances to return to the past.
The rules are cruel yet tender: she cannot change what has already happened. She can only spend 24 hours on each designated date, "rewriting" new memories for moments filled with regret. From taking her first steps at one year old to rebelling as a teenager, she tries to embrace her taciturn father in the gaps between moments in time.
This is a heartwarming story about family, regret, and forgiveness. If time has an echo, it must be shaped like love. Seventy days of echoes bring seventy reunions between her and her father, across the divide between life and death.
