I'm sorry, but I just don't like you," my fiance told me coldly. Not only was she shunned by her family and had no place to belong, but her fiance was stolen away by her half-sister, Erica. On the night her engagement was broken off, her father quickly arranged for her to marry a new fiance, hoping to get his hands on his fortune. The age difference between her and her new fiance, Earl Lister, is a whopping 15 years. On top of that, there are rumors that he is a "cruel Margrave" because so many fians have run away from him! But in reality, he is somehow very...kind and wonderful...!? What will become of this awkward love story between these two with such a large age gap?!
