"I heard it would be a 'white wedding,' but somehow... well, the story seems different...?"

Isabel, confessed to by the Duke Harald to "have a white marriage," nodded "yes" without understanding what "white marriage" meant. Three months after marriage, Isabel learned the meaning of "white marriage" through the absence of marital relations and became curious about why Harald had proposed such a marriage. Around that time, Isabel reunited with Sonya, a baroness and former classmate from the aristocratic academy, who called her a "barren woman." Not understanding the meaning of "barren woman" either, when Isabel asked Harald about it, he told her to "wait at night." What will become of the couple's married life?
