Yachi Hitoka was an astronomer from Italy, her hair was a mess as were her research notes and she was notoriously squeamish when it came to talking with people. After returning from her studies abroad, the duchess asks to meet with her about information regarding her findings. Kiyoko Shimizu owned a manor that took up nearly an entire block, she had rooms in which each wall was covered from top to bottom in books about astronomy and things of that sort. The topic fascinated her so. She was self taught so to speak, her family always tried their best to keep her away from books and they gave her the simplest education possible. But after they've long since passed away, she consults an old friend of her's whom she thinks might be of some help. *although I've changed a few things up, this plot is adopted from a book called 'The Lady's Guide To Celestial Mechanics' which I definitely recommend reading* *contains mature themes later in the fic* *some language*
