First sentence of Feel 100%

鬧市中，一切高速流過。許樂茫然站在其中，仿彿全無感覺。

So 許樂 is in a bustling market and generally unaware that he lacks feelings?

I feel like I'm probably missing something here.

I've already scanned through the book once and most of the dialogue is easier to understand than this. Still, I'm sure I'll be back with more.

Thanks!
