Linon and Garance are best friends with very different ideas about love. To get to the bottom of what all this romance stuff is really about, they decide to conduct an investigation into some of the older students at their middle school. Why are certain kids more popular than others? Why do some already have a "bad reputation" by the 8th grade? Why is everyone so obsessed with appearances? Along the way, the pair discover that, for best friends who are supposed to share everything, they've both been keeping some pretty big secrets of their own.
