Patharamattu

As the story unfolds on the auspicious occasion of Onam, the paths of Kanakadurga's daughters and the Moorthy brothers intersect. Nayana, with her artistic skills, ventures to decorate the walls of the Moorthy household, accompanied by her covetous mother, Kanakadurga, who harbors hopes of securing prosperous matches for her daughters.

In the opulent setting of the Moorthy residence, the dynamics of the family become apparent. The three brothers, each with their distinct personalities, form the nucleus of the family. Aniruddh, the youngest, captivates with his poetic prowess, while Abhinand exudes a carefree demeanor, often overshadowed by his envy towards Adarsh, the eldest brother and the family's pillar of responsibility.

Amidst the festivities and preparations for Onam, the paths of Nayana and Adarsh cross, igniting a spark that neither anticipated. Nayana's talent and charm draw Adarsh's attention, and a connection begins to bloom, much to the chagrin of Kanakadurga, who sees in Adarsh the embodiment of her desires for her daughters' matrimonial prospects.

Meanwhile, Abhinand, fueled by his envy and desire to outshine his brother, plots to thwart any potential alliance between Nayana and Adarsh, aiming to secure his own interests in the process.

As the festivities reach their zenith and the bonds between Nayana and Adarsh deepen, the intricate web of desires, envy, and familial expectations unravels, leaving both families at the crossroads of destiny, where the choices made will shape their futures irrevocably.
