Mistletoe and the Lost Stiletto(2012)

Glass no Pin Heel

Engaged to a bigwig in the fashion industry and selected as the face of a new brand, Lucy is as happy as could be. Until she stumbles upon some documents and discovers the horrible truth. Everything-the rebranding of the company, the proposal and her selection-was a part of the plan. Fueled by anger, she bursts into the press conference announcing the new brand before running away with the evidence. When she runs right into Nathaniel Hart's department store, he dodges her as she barrels past, but for some reason, he feels compelled to go after her...!
