My Wonderful World(2016)

Boku no Subarashii Jinsei

Shinobu Asakura has never been able to read or write—and not for lack of trying. It's made getting and holding down jobs difficult, and he's constantly berated by people who think he's simply slacking off when he's just trying to keep up. But a chance meeting with a café worker who introduces a new word to Shinobu's vocabulary—dyslexia—may just change the course of Shinobu's life forever.
