Side effects of love

They say my eyes shine
It brightens up their day
Its because hes all mine
I wouldnt have it any other way
They say my smile has life again
And its all because of him
He came when i needed a friend
Suddenly my world wasnt dim
He worked his way into my heart
And caused butterflies inside
I knew right from the start
Its something i cant hide
He was sent to set me free
He came from up above
The butterflies he gives to me
Are side effects of love
