Season 1
Hae-jun, a man with a cynical demeanor, works as an anchor at a news station. His unique personality can be attributed to his mother's abandonment when he was young and his grandfather's constant criticism, considering him the only flaw in their otherwise flawless family. Despite his grandfather's ignorance, Hae-jun rises to success in his career as a righteous reporter. However, his world is turned upside down when he unexpectedly comes across a time machine, something he never thought could exist. Yoon-young leads an ordinary life as an editor at a publishing company until she discovers her mother's lifeless body by a riverside. One day, her life takes a drastic turn when she gets struck by an invisible car near the same riverside and wakes up in the year 1987. The two gradually come to understand that the recurrent coincidences between them carry a deeper significance beyond mere chance.
