She falls from the third floor, and a handsome man happens to pass by. A shrewd, forceful soul takes the place of the sickly, timid girl who once lived in that body.

She has eyes only for the cold, heartless Imperial Preceptor. All she wants is to follow her heart and spend her life with the one she loves. But one day, she discovers the secret shared by the Imperial Preceptor and the young master... and falls apart...
