Oi Treis Harites (1990)

The Haritou family's ancestral home was initially inhabited only by the unmarried youngest daughter, Irini. However, in the first episode of the series, her older and widowed sister, Olga, moves into the same house until the construction of the new house she is building is completed. Although initially they thought that her move would be temporary, it eventually became permanent for the entire series. At the same time, the middle daughter, Maria, decides to move into her ancestral home and stay with her sisters, because she caught her husband, Yannis, red-handed with her best friend.
