Coka, I'm Fine

I am so sorry I have no time to call you.
I've been so busy recently and I don't want.
Do you recall the park where we've spent for whole night?
We walked and talked till the sunrise.
Public exam's coming, you've got to be hard working.
You should not be as lazy as I'm being.
I will always stand by you; so don't be afraid though I can't give you any note.
Coka, Coka, Coka, Coka, if you still remember me, just call me when you are free
