Reincarnated as the neglected wife of a duke who secretly loves the novel's heroine, she plans to divorce him to survive. Yet, he desperately begs her not to leave, confusing her as the story unfolds differently than she remembered.

I have always thought that this normal peaceful everyday life would go on forever. —until the day I met with that incident. Even if I had a fight with her, everything would be fine if I just apologized. —until she was abducted by a huge red dragon that evening. And, when I realized it, I was in a weird library. At first, I could not grasp the situation, however, soon I found out that library was a magical library with books which hold everything in the World. I tried to return to the original World —where she is in— however, the World Book I was in was partly destroyed and I could not return. In attempt to protect my own World, to rescue her, I set off on a travel to fix the Book.
