At graduation, villainess Silvia happily welcomes her engagement being broken off by the crown prince, even responding with, “Yes, I’d be delighted!” She clears false accusations through a humorous dungeon alibi and retreats to rural life with her compensation and S-rank adventurer license in hand. However, her slow life is disrupted when the crown prince’s younger brother appears—claiming to watch over her for the royal family, and overstaying… thus begins a quirky slow-life romantic comedy.
