After overcoming Nevel's harrowing cold, Lapter's spies, and an unexpected betrayal, Princess Rosemary von Velfalt successfully recovers the stone containing the demon lord and returns home to face her father. Since her accomplishments have proven her worth, the king fulfills his promise and offers her the right to choose her own partner...but gives her only six months to seal the deal! Now comes possibly the biggest hurdle of her life—winning Sir Leonhart's heart. On top of that, there's the problem of the demon lord in the stone, and only Hidden World's heroine, the shrine maiden, has the power to truly remove this evil from the world. With the summoning of the shrine maiden imminent, can Rosemary permanently break her flag for arranged marriage in a mere half year's time? Or will someone else steal away Sir Leonhart, along with her freedom?
