Change of Heart

There are people who believe there is merely but one.
The person who points your way to the endless sun.
The missing puzzle piece that makes them complete.
A rock that grants support when facing looming defeat.
What if one lost the matching half of their soul to fate?
Wandering hopelessly yearning on the road never straight.
But what if one’s heart could change shape and design.
Perhaps then another key would unlock the secret shine.
