Payak Rai Hua Jai Jiew

At the mansion of two bachelors, Pakrak and Pakaon, chaos ensues when their elder sister, Pakpak—the head of the Phithakmualchon family business—dies suddenly in a car accident. She leaves behind three young children and a mountain of business troubles for Rak to handle alone.
Aon, Rak’s younger brother, is against bringing the three children into the house, fearing women might mistake them for his own kids. However, Rak insists that his nephews and nieces are far too young for boarding school. Aon eventually yields to his older brother, fearing he might lose the position he had requested.
From the first day Sarim, Tabthim Krob, and Namchuam step into the bachelors' mansion, they bring a mix of mayhem and laughter to "Uncle Rak," providing a much-needed escape from his growing work stress.
The pressure is mounting due to Plamuek Yak (The Giant Octopus), a ruthless mafia figure nicknamed for his relentless attempts to devour the Phithakmualchon business empire. He dispatches his henchmen, Ittiphon and Amnat, to harass Rak and force him into selling shares at a low price.
Rak has another younger brother, Pokpong, the son of a mistress. After his mother passed away and he was kicked out of the house as a child, Pokpong worked his way through technical school. After a conflict with a manager at a corporate job, he decided to pursue an independent career as a motorcycle taxi driver. Rak continues to search for his long-lost brother, unaware that Pokpong is working at the taxi stand right at the entrance of his own street.
