Look Deeply, Feelingly

Behind every smile, there's always something that lies beneath it. The truth is we might never know. Some people fake their smiles. We can fake smiles and pretend like we are feeling happy when the truism is ,our heart is breaking, hurting badly yet no one knows.
Smiles may lie, but not eyes..

I once read a fanfiction and there was this line that says;

"At first sight, you may only see one's eye color.. But if you look deeply into the eyes, you could actually see happiness, regret, repent, hurt or hope..."  

Look, search into their eyes real carefully.  

What do you really see..?
