Heunhan Hwansaengnyeoui Sajeong

Valerie thought she’d be a genius mage in this world. But when her magic can’t get past basic and her teacher shares a prophecy of a tiger coming to attack(!!), she opts to enjoy an ordinary life. Everything’s fine until she’s engaged to none other than Duke Kylus Dwello. It’s just one thing after another—the mysterious Serena, the servants who ship the duke and Serena, a prince who doesn’t understand boundaries, and even the duke looming over her bed! Can she get back to her nice, quiet life?
