Inexperienced and quiet college student Tessa Young's (Josephine Langford) world gets turned upside down when she meets Hardin Scott (Hero Fiennes Tiffin), a mysterious and brooding bad boy who makes her question everything she thought she wanted out of life. Like "Fifty Shades," the sex scenes get steamier with each book (and movie), so "After We Collided" and "After We Fell" get even hotter. Plus, just like "50 Shades," "After" was born out of a fan fiction, though rather than "Twilight," this one was written about the boy band One Direction, with the character of Hardin originally based on Harry Styles.
