Turning the Situation Around

A moment ago.

"This is…" the student gasped, finding the log that Nathan asked earlier. There were a lot of words inscribed in it.

"I'm sorry, Rudeus. I can't afford to do everything as you said. Even though I can burn the side of the island opposite to yours, I don't want to burn the only water source on this island. Humans can live without food for two weeks, but they won't survive longer than three days without water. I've come to realize that I'm unable to do such cruel things, and I regret the fact I've promised you to burn that side of the island. You've truly forced me to become the villain of the class, Rudeus. I'm disappointed."

"Rudeus? But the only one who can write this is… that guy, Nathan!" His friend gasped. They were scouting the area ahead, hoping to find Nathan.

The only thing they found was a small lake and this log.

Both of them exchanged looks.

"Don't tell me, they have a secret agreement?"
