From a book club in a secret library to outings to magic device shops, Louise manages to regain the light in her eyes with the time they spend together. With her feeling her heart beat from Lucius’s sweet words, just when you'd think they’d get together in no time, the past that the ‘substitute lady’ doesn’t want to be known becomes an obstacle. “What do you think about this?”(No… I couldn’t possibly tell him about that.)On the other hand, Louise’s potential as a researcher is also starting to bloom…? A lady who loves magic devices and an iron-masked prince, a pure love story filled with misunderstandings!
