Stand-In Bride: The Time-Limited Duchess

Claire, the eldest daughter of a poor marquis family, is proposed to by the young Duke Hilaire, the country's most nobleman, to enter into a contract marriage for a limited period of one year for a certain reason. Surprised by the sudden proposal, Claire accepts the contract marriage and becomes a duchess, but is bullied by the servants soon after her marriage. However, having been mistreated by her family for many years, Claire does not give up no matter what happens, solving numerous problems and gaining allies. At first, Hilaire thought Claire was an odd woman, but before he knows it, he finds himself watching her closely. A frustratingly sweet love story that begins with a false marriage.
