The Useless Saint and the Cursed Holy Knight

Annabelle is a holy priestess When her "divine power" to heal suddenly diminished, she was seen as "useless." Without her power, she was forced to marry a rich nobleman for the sake of the church and to repay her debts. Hoping to make a happy memory for herself, Annabelle went out to the flower festival and confessed to a handsome paladin she met by chance. She was resigned to accept the unwanted marriage, when that paladin Luca suddenly showed up at the church and said, "Miss Annabelle, please marry me." "...... Huh?" She was shocked by the sudden proposal, and she noticed something even more surprising. "Why is a paladin cursed?!" "I'm sorry, but I was cursed against my will." Can the holy priestess without her divine power break the paladin's curse with the power of love instead!? (Source: Kodansha, translated)
