Sisyphus: The Myth Season 1 Episode 1 aired February 17, 2021 on JTBC as the premiere of the 16-episode series.

Park Shin-hye's Kang Seo-hae arrives from an implied future with clear urgency and no exposition. The episode works because the writers trust the premise to generate interest without over-explaining it - a trust the back half of the season would not entirely justify.
