Point of view: The first person who is a robot-like boy
Conflicts: The protagonist vs. the gravity. He tries to save the water in his body, but when he leans too forward, it all drops and leaves nothing in him.
Climax: The boy sticks something with a pipe, which looks like a heart. Out of the heart, a gold fish falls down on the floor. He picks up the fish and brings it in his empty body. Then, when he looks down, a sea of water fills them around.
Symbol: Water or the sea must be something that represents how desperately he wants a friend. At the last scene where the the boy and the fish seem to be comfortable in the sea , the sea shows how satisfied the boy feels with a partner.
Irony: There is nothing to stem the water and save it up in his body. No matter how many times he tries to get the water in, it all falls down in vain.
Theme: This teaches me how important a friend can be. A hearty friend can fill you with a secure feeling like floating in the sea.
