The latest season of Netflix’s Bridgerton, which premiered on January 29, is a reimagined Cinderella story. Adapted from author Julia Quinn’s novel series, the new season follows Benedict Bridgerton, the second oldest son of a well-established family in Regency-era society, and his love story with Sophie, who has been made to work as a maid in her own house by her stepmother Araminta Gun, played by Katie Leung. Of course, no Cinderella story is complete without at least one evil stepsister – and actress Michelle Mao has the role down to a tee.
