Milaya de Lua is plagued by nightmares about her ancestor, Queen Gloria. But one day, her nightmares become reality when she is attacked by an assassin and wakes up 100 years in the past as the queen herself! Gloria has left her with a message and a mission: she must restore the Wish Stone to turn back time and prevent the kingdom from plunging into despair. Aided by the queen’s diary and a duke who knows her secret, will Milaya be able to save the kingdom and herself?
