Silver

You lazily cut through the waters, arguing about something of your own.

—There are few fish today.

Your comrade stated.

—It's better for us.

You said so.

After swimming a couple dozen more meters, you stopped.

• What are you doing with your fish?

You got angry.

He didn't have time to open his mouth before something rushed past. The water became heavier, as if it was squeezing you.
But in the heat of anger you didn't notice it.

Your friend began to gesture, looking through you.

• Well, what else?!

You said irritably and turned around.

There was a shark (Silver).

• Nerve cells do not regenerate, but this should no longer worry you.

Silver stated with a smirk on his face.
