She Thought I Was Family

DramaBox synopsis

Corporate heiress Vivian Hayes discovers her husband Evan is cheating with Chloe Grant — and Chloe mistakes Vivian for her mother-in-law. Vivian plays along, becoming the most ruthless "mother-in-law" imaginable: designer shopping trips, brutal house rules, and a black card frozen at the worst possible moment. When Evan finally shows up, the game is already over.
