I think of the love of Laguna and Juliathart never had a chance reborn as the love of Squall and Rinoa after Laguna and Julia lived a happy life with Raine and Fury before Julia and Raine died. The reason for Eyes on Me, a song for Laguna to be played for their children's love.

Then we have the fear of the loss of love embodied by Squall after Ellione left him so only Rinoa was able to change him.
