tout sur is a french word that means "about" or "everything on"

"I love you, Ashton" I whispered to his sleeping face, being careful so he doesn't hear. Quickly kissing him on the cheek, I run away knowing that he can't know, and he will never know. I'm in love with my bestfriend. "Diana?" Ashton's voice stops me. Tears threaten to fall down, but I push them away. "Yes?" "Could you please call Mel?" He replies. I nod and walk away.
