Kaneki: ....the sweet taste of blood coated my mouth. I kept walking, my goal vague...trying to dispel the building unease in my chest...
I can't believe Hide is dead.
Kaneki: Why is it that the beautiful things are entwined more deeply with death than with life?
We won’t be able to walk together like we used to anymore.
Kaneki: Human relationships are chemical reactions. If you have a reaction then you can never return back to your previous state of being. I wish I could bring him back.
Kaneki: Please, Hide, don't be dead.
Kaneki: I’m so lonely without you....
Kaneki: I’m consumed by the desire to meet you again, so much so that I cannot fathom a path on which to follow.
*clears throat and brings up a notepad instead*

Kaneki: Hide; why are you alive?
Based on this post on the show ‘Shiki’ and the equivalent of Hide in it:
Warning, Shiki spoilers, it’s best you watch that show first.
