A tranquil lake surface. At the bottom of the lake, there is an abandoned bottle and a small fish. The fish swam into the bottle. From then on, the two depended on each other for survival. The bottle thought it was love, but the fish thought it was friendship. Until one day, the fish grew up and realized it couldn't get out. The bottle, however, crashed into a coral. As the glass shattered, the bottle said "I love you". The fish cried, but it was all over.
