Hayato and I don't get along. Calling it "not getting along" is an understatement; we're bully and victim.

I've been insulted, had things stolen, been mocked, and at worst, even beaten. Despite that, we ended up in the same room for our school trip due to a lottery. And it's just the two of us.

Tonight is the third night of a four-day, three-night trip. Once today is over, I can go home tomorrow.

I've been stuck in a room alone with Hayato, the bully from my class, but I've managed to act like an adult and get through it without incident.

I was hoping it would stay that way until the end...

The incident happened on the third night.

I accidentally forgot to flush the toilet.

Hayato flew into a rage and tried to strike me, so I instinctively punched him back. To protect myself, I forced him to swallow the sleeping pills I keep on hand for emergencies.

After a short while, Hayato collapsed onto the bed and slowly closed his eyes.

I've really done it now...
