What if the cracky that existed three years ago is not the same anymore? Are you infatuated with a shadow of the past? In fact it is more likely than you think. You are all older than 14, and you all know that the age 13-15 is a time when girls begin to explore their effect on the other gender. Dont you remember that girl in your class with the slightly awkard make up trying to seduce you with her cuteness? Cracky did it so much better. And she did on the web with added nerd appeal.
But you also know that three years later everything was/is different. And so is Lia. You keep a shadow of her past alive.
