In the kingdom of Faucigny, Duke Dreux is a man feared by all, earning the chilling title of the 'Grim Reaper' for his ruthless nature. When Nöel Montbelliard finds herself at the end of his blade, she expects a swift death—until a stray magic spell changes everything. In the blink of an eye, the cold-hearted Duke is transformed into a blushing, doting, and hopelessly obsessed 'puppy' who treats Nöel like his entire world. But this fairytale transformation comes with a dangerous catch: the magic is unstable.
As the spell begins to wane, the Duke’s personality starts to fracture, leading to extreme emotional whiplash. Nöel is forced into a chaotic life where her husband might be whispering sweet nothings one moment and threatening her with a sword the next. To stay alive, she must maintain the facade of a happy marriage while searching for a way to stabilize the spell—or find a way to make the real Duke truly fall for her before the magic disappears forever. The series expertly blends laugh-out-loud comedy with high-stakes tension, making every interaction a gamble for the protagonist.
