Why it has to be you?

Sitting alone and silently
I recall a special part of my life
That part came unexpectedly
And lasted only for a while.
My life has been quite and peaceful
Until that unforgettable moment
You came like a silhouette of my soul
Then you walked right through my heart.
Everyday was a picture of happiness
There's no hint of loneliness
Everything was wonderful
Because I spent it with you.
But then, as time goes by
Feelings begin to fade away
Tears fall down one by one
And it kills me to say goodbye.
Every time my mind says move on
my heart says hold on
So many questions inside my head
But the answers are all up to you.
Loving someone like you
Without boundaries
Makes me think deeply again,
Why, Why it has to be you?
