Obsessions [3]

Pain. 

What was pain? 

Was it just the physical or emotional distress that arose in response to an event such as injury or death? Or was there more to it? 

I wasn't too sure myself. 

All I knew was that I'd have to experience pain in order to become stronger.

This was the fastest method I had available. 

Flip, flip—

Each time I turned a page, I felt myself become stronger. 

But at the same time, 

"Ukh—!" 

I also felt an unbearable amount of pain.

There were a total of 158 pages. 

Each page brought a new wave of pain, yet with every surge of agony, I felt my strength grow. It was as if the suffering was a catalyst for my power, serving as some sort of anchor that prevented me from going insane. 

It also made me think about pain. 

What was it, and why did I make myself go through it?
