Untamed

"And I'll be gone, gone tonight
The ground beneath my feet is open wide
The way that I've been holding on too tight
With nothing in between."

 When you realized everything was just a dream that you can never go back.

"Although I am broken, my heart is untamed, still."

Maybe the time wasn't long enough for everything to be changed.

 a story that can't be explained.
and i found the reason for that ending
because a choice was too difficult to make.
and giving up everything became the best choice of all.
To follow what your heart says you need to know what's inside your heart.
and yea. your heart doesn't transcript or translate like DNA.

[A choice is so hard to make]
