The boy I hate the most

I believe there's a saying that " There is a very thin line between passionate hate and true love" and sometimes you don't know when you cross the line of hate to love.
And you come to realise only when you are in a deep trouble and that's when you are completely fallen for the person whom you hate without knowing that you have fallen deeply in love with him.
And what's the worst scenario that you come to realise when the person has gone away from your live .
And still after many year you can't forget him .

What does the future has stored for them .
Will they meet .
What are the hidden secrets of both are hold in future for them.
Are they gonna become lovers because they are completely opposite to each other.
Never confessed there felling.
