Bert is slight and wears glasses. But Bert’s mighty cool, too. That’s why the only girlfriend he can think of is the coolest girl in school – Leila, star of the basketball team and a commercial for yogurt. But unfortunately, Leila is already going into the ninth! So what to do? Luckily, Leila’s sister Amira goes to the same class as Bert. To get close to the big sister, he befriends the smaller one. But is that really fair? And how fair is it to read other people’s diaries? In any case, Bert triggers many small and large catastrophes with it. But for guys in love, the age-old rule still applies: you can’t make an omelet without breaking eggs!
