Based on the Korean manhwa "Kimchi Mandu", Hello, My Lady! is a comedy that puts a traditional Korean family up against a nouveau-riche Korean family with a grudge. Lee Soo Ha is the 38th granddaughter of the Jae Ahn Lee clan and the owner of a traditional Korean manor. She's doing her best to keep her family's traditional values afloat and save her home from going bankrupt. Hwang Dong Gyu is the eldest grandson of the conglomerate TOP Group, and he wants to snatch up Soo Ha's manor to give to his grandfather, a former servant at the manor hell-bent on dying in the master suite. Dong Gyu tries to convince the stubborn Soo Ha to sell, while trying to fend off his rival and cousin, Hwang Chan Min. But model Seo Hwa Ran also has her eye on the manor, not to mention Chan Min.
