It Was a Mistake, Grand Duke!

Histoire

Vivian Louis is the twenty-one-year-old daughter of a Count, a sweet and seemingly harmless girl who has only one guilty pleasure in life: thirsting after her crush, the breathtakingly handsome Grand Duke Lennox Elphidion Glenn! For her, it was love at first sight at the tender age of fourteen. That’s when she began obsessing over him, creating endless works of fan art and fan fiction. Then one day, an accident with her best friend’s magical crystal ball makes the unthinkable come true. The grand duke is kidnapped and tied up in her bed, and he’s telling her that she’s the kidnapper!
