After you were done meeting Four, you became friends with him.

You then took a walk on this strange world as if it was normal since people here are numbers or you should call them.. 'Algebraliens'..

While you were taking a walk you noticed another number that seems to be sitting by themselves at a bench.

You walked towards the number and it noticed you.

He stood up immediately just like what Four did and the blinked once as a greeting, you started to think that it was natural for them to do this.

"Hey! I haven't seen you before, so it's nice to meet you whoever you are!" He said with a happy tone, you realized it just had a British accent.. But you really don't mind at all. It didn't seem to know about humans as well since you also noticed that he was staring at you curiously.
