A line between us

What is this line that links us two,
Invisible and thin,
It looks so small, so long infact for one single piece if string.
Pink, no white, the color of the line, it shares the colours of our hearts, as they are one devine.

Are hearts have bound to make a string to stretch so far between,
The two of us are connected now and forever more to see.

the string will snap one day for sure,
because of heart break or a death,
The end of the string is not in sight,
Let's just say, "We begin"
