Mrs. Park is Chi Park's mother and Kwansik Park's wife. She is briefly seen at the end of Gut Check. She is a Filipino immigrant.
Chi and her mother do not get along very well. Mrs. Park expects Chi to take care of her grandmother Popo during her time off. This led to a temporary estrangement between the two which Robert Chase repaired by offering Chi refuge in his apartment, then befriending Popo and reminding Chi that he didn't have any family at all.
