The Housemaid

Daisy is hired as an au pair for Roxanne (pregnant with twins) and her rich husband William. Her primary task is watching the couple's young daughter, Nami. Daisy is eager to connect to Nami, who gradually warms to her. William begins to secretly flirt with Daisy, enticing her with glasses of wine and his piano playing, and they eventually begin a sexual relationship. Despite the affair, Daisy is still warm and friendly to William's oblivious wife, Roxanne; she even expresses enthusiasm and delight at the progress of Roxanne's pregnancy.
