Rira, the daughter of the Tachibana family, is on the verge of ruin, oppressed by her family and not allowed to walk in the sunlight. The only way to escape from her household is to get married, but her potential spouse is a perverted old man who admires Western dolls at night. Just when she thought she had no choice but to endure it, Rira finds out a weakness of Azumi, the eldest son of the famous Nishioka family, and proposes to him. Without realizing that this marriage would be troublesome, the story of a marriage between a strong-willed daughter of ruin and a reclusive son of a duke begins! (Source: Flower Comics, translated)
