This was such a fun magical romance. Catherine was recently hired as a mathematics professor and learns that she doesn't exist according to the government. Her doorman, Luca, jumps in and helps get to the bottom of it. 

The story is a big wild goose chase as they meet various members of Luca's family. I really enjoyed seeing Catherine's growth and understood her desire for stability and schedule and how she learned to live life. 

There are so many fun moments between Luca and Catherine as well as the residents of rhetorical building.
