Jang Sae-byuk is a cheerful and grateful orphan who always tries her best. She dreams of one day becoming an interior designer, despite her lack of education and money. Because of an accident that happened before the story starts (about three years ago), she loses her sight and undergoes corneal transplant surgery. Different events unravel when she encounters the Kim family, who has lost a daughter in a horrible car crash, unbeknownst to everyone besides the father and older brother. The stories then intertwine when Sae-byuk meets the Kim's extended family and the son of a big interior design company, Lohas, in Korea.
