Cecile, a talentless White Witch, leads a humble life after being deemed useless in the world of magic. However, during a grand party, she makes a catastrophic mistake—accidentally spilling a homemade antidote on Oswald, the First Captain of the Templar Knights and the most sought-after man in aristocratic society.

But this wasn’t just an accident; she had sensed a powerful dark aura emanating from him. Instead of receiving an apology, she suddenly finds herself kidnapped and taken to his mansion! Fearing for her life—or perhaps something even worse—she is shocked when Oswald coolly dismisses her worries with a chilling statement: “You’re not my type.”

Cecile soon realizes that Oswald isn’t interested in her, but in the antidote she used on him, as it was the only remedy that had any effect on a mysterious curse afflicting him for years. When he offers her a formal agreement to assist him, she sees it as a chance to finally prove herself—and decides to accept!
