During a party, Cecil, a low-ranked white mage, sprays a homemade potion into the face of Oswald, the handsome captain of the First Paladin Squadron and the most eligible bachelor in high society. She only did it because she could sense a strong taint of evil emanating from him, but an angry Oswald forcibly takes Cecil back to his mansion. She thought that her chastity might be in jeopardy, but he brushes her off, saying, "You're not my type." It turns out Oswald's true purpose is to learn more about Cecil's potion, which is the only medicine that has been effective against a cursed wound he received in battle. When Oswald formally requests Cecil's help, she decides to take advantage of this chance to make her mark as a white mage! A romantic comedy between a cursed holy knight and a clumsy white mage is about to begin! (Source: Comic Zero-Sum, translated)
