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
