Rosie (Lily Collins) and Alex (Sam Claflin) have been best friends since childhood. They do everything together and confide everything in each other. As they reach the end of high school days it is clear they each have feelings for each other secretly, but cannot risk revealing how each feels. They help each other win boyfriends or girlfriends, prepare for the school dance, even discuss sex very frankly. Underneath it all, it's still very clear to the viewer that it's all about them. This movie is a good romance.
