Movie's information

The Synopsis:

One summer, I was filming by the seaside, and I met him. I was playing as a floating dead body. He thought that I committed suicide by drowning, and “saved” me by the seaside. I fell in love with him right away. We went to watch all the movies I loved; I talked to him about my fascination with death. I asked if he would come to my funeral after my death. He could no longer bear with that and left me. After all the incidents, I sit in the theater, looking at the big screen, watching our stories taking place, and realize that everything is my imagination. Yet, I would love to stay in that fictional story.
