I need to ensure that each film discussed has a clear connection to romantic or relationship storylines. Also, avoid mentioning films where her role isn't centered around romance. For example, her role in "Thalapathi" (1991) might not be as relevant here if it's more about action or drama than romance.

I need to verify some details. For instance, the plot of "Sivakavi"—it's a historical love story where she plays the daughter of a king, so the relationships there are political and personal. In "Engamma Gandhi," the title character is a woman in a patriarchal society, so her romantic relationships might be more about resistance and asserting her independence. That could be an example of a strong female lead in a romantic narrative.

I should also touch on the cultural impact of her romantic roles. Were there any iconic scenes or dialogues that became legendary? For example, some of her films might have popular songs or sequences that became benchmarks in Tamil cinema for romantic scenes. Including examples could give the piece depth.

The user might also be interested in how her real-life divorce with Gemini Ganesan affected her filmography. There's a possibility that her roles post-1964 might have explored themes of women's independence or emotional resilience more, but I need to check if there's evidence for that. Alternatively, her characters might have consistently portrayed strength and poise regardless of personal circumstances.

Additionally, her co-stars' styles might have impacted the chemistry in the romantic scenes. Gemini Ganesan was a versatile actor, so their on-screen chemistry could be a highlight. After their divorce, she might have been paired with different actors, and the dynamic might have changed. For example, her work with M.G. Ramachandran (MGR) in films like "Puthiya Vaara Puthiya Natkal" (1980) might be more about political themes, but there could still be elements of family and societal relationships.
