Shammos's Regained Memory

The missing pages were a great help. I think I'm starting to understand who I am. But still, my memory comes and goes. While I write this, I am sane. But who knows when I'll lose my mind again. I have a bad feeling about all of this. If what I've learned so far is correct, something very dangerous is about to happen. I need your help, friend!

From Shammos

It is good to see you, [이름], my friend. It is strange. The more I remember, the stranger I feel. And this strange feeling makes me want to go insane. That's why I wrote to you.
