Lyrics:

So many times, I've tried to make you understand
You never tried to see behind my smile

If I didn't know you like I do,
I'd let you into the secret in me
Just because I'm good at fooling you
When no one's around, I walk in your shoes

I'm smiling while lying to you
I'm smiling while lying to you
If you only knew...

I always try to hide behind a painted smile
So many things the public never sees

If I didn't know you like I do,
I'd let you into the secret in me
Just because I'm good at fooling you
When no one's around, I walk in your shoes

I'm smiling while lying to you
I'm smiling while lying to you
When will you see through?

I'm smiling while lying to you
I'm smiling while lying to you
If you only knew...

I'm smiling while lying to you
Won't you soon see through?
I'm smiling while lying to you
If you only knew...

I'm smiling while lying to you
Would you concede my smile?
I'm smiling while lying to you
If you only knew
