This is a story of retribution, triggered by a single letter. Five years have passed since the villainess Leena was exiled. Now, a letter from her arrives for the Crown Prince—her former fiancé and the man who condemned her. The Crown Prince could not hide his irritation at the contents, which read as if the public denunciation had never even happened. At the same time, similar letters reached others involved in her exile: the commoner-born Crown Princess, the Count's daughter who was once Leena's best friend, and the Crown Prince's personal knight. Fear, contempt, joy—their reactions varied, but the letters spurred them all to begin searching for Leena. Little did they know that this would be the beginning of their fall from a life of peace.
