Han Song-jung is a novelist and single mother. She raised three daughters on her own and is determined to marry them off to decent men. But in the end, Song-jung finds herself getting married as well.
Jung Da-ae is the eldest daughter; she is the perfect bride material—not only beautiful and smart, she also helped raise her younger sisters with loving care. Jung Da-jung is the middle daughter, a girl overflowing with warmth and boundless optimism, who cheers up anyone around her. Jung Da-in is the youngest daughter.
The family next door runs a rice cake store, and their eldest grandson is Seo Jae-woo. Jae-woo earns a steady income as a salaryman at a large company, and has some brusque and conservative traits he inherited from his grandfather, but also some sweet gentlemanly traits from his father. It makes him rather stuffy and old-fashioned, but he's a good guy, and becomes romantically involved with Da-jung.
