In Tamil heritage, the marumagan is often treated with the highest level of hospitality. Upon entering his wife’s maternal home, he is traditionally greeted with a "virundhu" (feast), symbolizing his elevated status. This respect stems from the idea that the son-in-law is the guardian of the family's daughter. A positive relationship between the mamiyar and marumagan is seen as the bedrock of a peaceful extended family. Evolution in Tamil Cinema and Media

These storylines are popular because they mirror the real-life complexities of the "Kootu Kudumbam" (joint family) system. Even as Tamil society moves toward nuclear families, the emotional tether to the in-laws remains strong. The mamiyar-marumagan dynamic offers a rich playground for writers to explore themes of ego, unconditional love, and the cultural transition between generations.

Modern Tamil soaps (serials) often flip the script. In these storylines, the mamiyar and marumagan team up to solve household problems or to bridge the gap between the husband and wife. This shift reflects a more progressive view of the modern Tamil family, where the mother-in-law acts as a mentor rather than a gatekeeper.
