Who-a robot or some kind of creature
When-in the future
Where-in a town. There are no other creatures like him.
Problem-he needs water to live, but if he takes the water, a fish will die.
Solution-he gets water, but doesn't want to kill the fish, so he puts the fish in his body. They can live together.
Message-I thought that the story had a lot of messages, but difficult to know. Maybe one of the message was coexistence because the last scene ends with that. The other message I felt was that, we have to think about the worth of water.
