While a commercial published book titled "Sneha Romantic Fiction Collection" may not exist on Amazon (yet!), the fan fiction community is thriving.
Penmai is the largest women's forum in Tamil. Under the "Short Stories" section, you will find threads dedicated exclusively to celebrity-based fiction. The "Sneha & Simbu" or "Sneha & Ajith" imaginary pairings are cult favorites. The stories here are community-vetted and often heartwarming.
Some collections take her classic films and expand them into novellas. For instance, a 30-page story based on Unnale Unnale might add internal monologues, alternate endings, or deleted scenes. These feel like "director’s cuts" in literary form.
