oh man as a math nerd and a slice of life bitch this was such a joy to read!! I absolutely adored spending time talking about the beauty of prime numbers with a nameless housewife, her 'root-shaped' haired son, and an iconic math professor.

I 100% want to reread this book at some other time though, because I read most of it at school (I tried to avoid reading it in math classes as a sign of respect to the Professor) and sometimes my mind would drift off and I'd lose focus :c

Ogawa Yoko san's writing was honestly super accessible (there was not One furigana throughout the entire book and I managed to get through it fine?????) without sounding too simple - it was like a warm comforting blanket that just poured love into me.

this is probably due to my attention span as aforementioned, but sometimes I felt like Hakase's memory went way over 80 minutes? idk I really need to reread some bits. and ngl, I was quite confused at the baseball scenes... I had 0 idea what they were talking about

definitely one of those books that I'll think about randomly at some point daily <3
