It was Amortentia's fault

When a prank is played, a spell is bound.
A spell so strong, a spell of love.
Broken by the one she loathes,
She's lost and all's forgotten.
She lets him know how much it hurt,
And walks away feeling like dirt.
He falls for her, but there's no prank.
The spell rebounds, he's gotta get her back.
With broken hearts and tortured souls,
And tears streaming down her face,
They're lost, don't know the way,
Will they remain or fade away,
Or pay the price for what Amortentia has made?
