Bou Alaywi decides to start writing a diary to record his daily life, and his wife, Um Alaywi, helps him get started. At the same time, he enrolls in a class with his friends to "expand his knowledge"—but with his unique personality, this might lead to more chaos than learning!

As Bou Alaywi prepares for a trip, he asks his friend Al-Aidroosi to manage his shop and gives him full authority, including responsibility for his wife’s needs. But when Bou Alaywi returns, he’s in for a big shock: Al-Aidroosi has transferred everything into his own name and taken over the shop! Bou Alaywi has to figure out how to reclaim his life’s work.

In his diary, Bou Alaywi dives into the subject of “women’s jealousy and suspicions,” which quickly leads to a clash with his wife, Um Alaywi. Frustrated, she leaves to stay at her family’s house. Meanwhile, Bou Alaywi’s friend Bu Mohammed finds himself in a similar argument with his wife over jealousy. Will Bou Alaywi finally understand why these suspicions bother his wife so much?

Bou Alaywi writes about his wife’s “talent” for giving unsolicited advice to her neighbors, which always seems to cause arguments and marital troubles for them. Bou Alaywi wonders if he can convince her to keep her “wisdom” to herself, but her meddling continues.

Bou Alaywi’s diary entry covers Um Alaywi’s pregnancy, his friend Al-Aidroosi’s role in ruining his chance for a work bonus, and—of all surprises—his wife giving birth to ten babies at once! But the twist? Bou Alaywi only receives five of them. Where did the others go?
