Princess Rosemary von Velfalt continues her quest to lead a peaceful life in the Kingdom of Nevel and win the heart of her beloved Sir Leonhart. Though she’s already stopped one war, enemies still lurk beyond Nevel’s borders, and the threat of a plague looms large. And then of course, there’s the issue of the malevolent demon lord... Or so she thinks, until one day her carriage narrowly avoids crashing into Michael, a goofy boy who happens to be physically identical to the demon lord’s game avatar! She’ll need to uncover this boy’s secrets to stop the demon lord’s resurrection, all while keeping an eye on the enemy at home—her own father. The king’s reward for all of Rosemary’s peacemaking and hard work turns out to be...an arranged marriage?! At least now she’s earned the right to call Leonhart by a nickname! The world may no longer be the same as the game that Rosemary once knew, but the friends she’s made along the way will help her skip story routes and achieve a bright future.
