"Completely"

It's just a slip of the tongue.
A simple line of poetry;
A lost language you made remembered;
A daydream lost in fantasy.
It was just a simple phrase--
The heartfelt words of one who's seeking.
The timeless promise made so pure;
The whisper your claimed wasn't fleeting.
It's just those words--they stole my heart.
They broke us in two so naively.
They bound us together like some sort of spell,
And showed me that your mine completely.
