What happened from my point of view
The video is about a boy who saves a fish and imagines that it becomes a mermaid. Little did we know that in the country where the boy lives, imagining is prohibited. As a result, the boy is tortured in an attempt to make him “normal” and prevent him form imagining things that are not real. After a brief period of forgetting what the mermaid looked like, the boy decides to escape and return to the place where he saved the fish. There, he remembers the mermaid’s appearance and decides to drown himself, perhaps because he cannot bear thought of being unable to imagine or because he is disappointed in himself for forgetting.
