Sijipeuseu: The Myth

Greek mythology: Sisyphus was the king of Corinth who was punished in Hades by having to repetitively roll a huge stone up a hill only to have it roll back down again as soon as he had brought it to the summit. This mundane task is also seen as a metaphor to laborious contemporary life and its repetition of modern society. This perpetual task is where the term "labour of Sisyphus" or a "Sisyphean task" derives.

Netflix Canada list this as Sisyphus actually a different Korean series about a cat.
