All is well in the life of AurÔelie Laflamme! In her family, it's total harmony (if we exclude the differences of opinion she still has with her mother about the household). Plus, since she's been dating a popular guy, her social life has been completely turned upside down. New friends, respect from her peers, outings, immunity when she makes jokes in class... What more could she ask for? Nothing. Except maybe a paranormal power allowing him to split himself. Because in addition to learning to reconcile school, family, love and social life, she will have to open up to new fields of interest (the sports practiced by her boyfriend), take care of her image (to integrate well into her new group), but, above all, to remain herself (not easy in this whirlwind). For a girl who has never been a specialist in mathematics, AurÔelie adds up the successes, subtracts a few friends, feels divided and multiplies the complications!
