I, a ragged young lady, am being proposed to by an elite count!? In a world where there's a legend that "a child born exactly at midnight on the night of the new moon will not live to be 18," Baron's daughter Miseria is born at that very moment. Called the "cursed child" and mistreated by her family, she is suddenly proposed to by the cold and ruthless "Ice Count" Gravis—!? A new Cinderella love story begins with marriage between a kind-hearted, oppressed young lady and a cold and ruthless count with a troubled past.
