I have hunted everywhere for this and cannot find any answer

I have a Asian video I got off of Youtube a few years ago and I have no idea what the son is. The song starts I think it is "Show me love forever"

this is how the story on the video goes

Swimmers in the ocean, a girl loses her air in her tank and washes up on a island and meets a man, he catches fireflies for her, later she cuts his hair, He makes a raft and they sail on the raft into the sea and a plane picks her up and then comes back and she jumps off the plane to be with him

If you know what the song or video is called pleast let me know

thank you
