I don't know..

You used to be the one I like
The reason why I smile
We seemed to have our past
But I know it won't last

I just realized it now
You're not my kind of guy
You've hurt me so much
How lucky you are to own me such

Day by day I see you again
Knowing in my heart, you left a stain
I don't know what to say
I just can't feel the feeling, I used to feel yesterday!!
