This also reminds me of another book that I read called Delirium by Lauren Oliver. Lena the main character lives in a society where love is a disease. And as always she found a guy that she likes. Its sort of like the Uglies by Scott Westerfeld. In a certain age they get a procedure to get rid of the disease, During the book she has to sneak out of her hours. Go to unknown parties, pass the boundaries and much more. They hid everything from the rules. Both characters had to be cautious getting around. All there evidence had to be burned. And they had to blend in with the crowd and not cause any concision to set them out.
I got a picture of someone hiding just like the characters.
