Sawako and Endou-kun discuss the book Sawako's been reading, Fermat's Last Theorem, in the café where Shiori works part-time.
You don't even know Heinlein!
!إنّك لا تعرفين هينلاين حتّى

Ni conoces a Heinlein.
Ni conoces a Heinlein.
même Heinlein t’échappe !
Non sai nemmeno chi sia Heinlein!
Nem conhece o Heinlein!
