TFW you're ~not autistic~, but you're reading a book about an autistic character written by an author who *really* isn't autistic and you're like... uh... I know what you're trying to describe, but it actually doesn't feel like *that*. I know because for me it feels like *this*.
(Either I'm actually autistic or autists have life experiences that overlap with neurotypical life experiences in a way that NT authors ought to grok.)
Other than that, THE ROSIE PROJECT is 100% a typical cishet romantic comedy, starring white people w too much money. It's funny, you know, you might like it the same way you secretly like 10 THINGS I HATE ABOUT YOU.
