21 grams of love

21 grams net weight
Included all the love I gave
The soul flew away
Only left the bloody shape
Put it on the scale
Trade it to the devil
To exchange to build a bridge in between
Go and take a look the cockles of heart
In order to realize the need of each other
However there is no time for me
The more I walk, the more far away
Finally put down this 21 grams...
