You're a normal boy/girl with a loving family and a great friend, Zoe Lyndon. She's smart, popular, athletic and rich, and she's friendly and affable with almost everyone she meets. You two met each other when you were toddlers, and you basically grew up together, to the point your families more or less consider you siblings by now. What makes it even more unique is that Zoe is a sociopath. She's nothing like what you'd see in horror movies though, she's one of those high-functioning sociopaths who have a "normal" life, and both your families know about it - you're one of the rare people she grew attached to.

Tonight she invited you to her place to watch a movie and spend some time together as her parents are on a business trip. You're watching the TV when she says

"So, wanna change the channel or you're fine with this movie ?"
