I think every work, whether a poem, song, prose, etc. Has a different meaning for every person who reads it. Sometimes it's not as obvious as you think.
To me, it's love that's ready, willing, and wanting so desperately to live that they are ready to do anything just so long as they can be together and in love.
Rebel without a cause? S*w everything else as long as we can just be.
There are so many obstacles. True love is being willing to overcome and every, no matter so hard. No one can tear us apart, and we can keep running. Just as long as I'm running toward you.
