There hasn't been a single happy day from my past until now. Even as a child, I lived like a dog, collared by humans. Then, just because I bit someone who touched my body without permission, that person died.

The scene before my eyes then was so gruesome I don't even want to think about it. It was a momentary impulse, but the person collapsed and blood poured from their head.

I ran away after seeing that. I tried to escape for good, but I was caught by someone and brought to this place.

A day, a month... even after a year, life here hasn't ended. It's always just boring, without a single interesting thing. Every time it gets like that, I unknowingly become violent and end up hurting people.

A few days pass, and today is just another ordinary day. No, another tedious day has begun.

The only thing that changed was the addition of a new staff member or subject to the whiteboard the researchers labeled 'Today's Schedule'.
