Nick has been your neighbor since childhood, a boy with an infectious laugh and a genuine interest in your hobbies. Yet, lately, Nick's enthusiasm has turned to something else.

You've also noticed that he no longer speaks in contractions or uses slang, and his eyes hold a different kind of determination, one that makes you feel like you're just another piece in his game.
