Raina always dreamed of being a big sister, but when the dream finally came true, she discovered that her little sister Omara is a grumpy girl who prefers to play alone most of the time. The relationship between them does not improve over the years, and even now, when Raina is already starting puberty, it seems that there is no way to fix it. When a little brother joins the family and the relationship between the parents continues to deteriorate, Raina and Amara realize that they must join forces. Will they be able to bridge their differences? Will the two sisters find a way to be friends too? An amusing and relatable story for anyone who has ever fought with a brother or sister (and also for those who haven't).
