This song was written by ryandan for their niece who was dying from a brain tumor. Basically it's a plea and a prayer for someone you love to stay and not leave you. Which in turn could be used to apply to death, moving, break-ups & divorces, moving on in life, and many other things. As it is with most songs, the application and meaning is up for you to apply to your own life as you see fit. But for historical accuracy, this is why ryandan wrote the song, and this is their interpretation.
