Heartin

The film begins in Rajasthan's Jaipur, where Shiva (Sananth) owns a Tamil food joint with his friend Mani (Whatsapp Mani). Shiva teams up with one of his friends for a heritage walk at Nahargarh. After their first encounter at the fort, a visibly enchanted (Don't ask how) Sadhana (Emaya T) uses the Tamil food excuse to frequently see Shiva. As sparks fly between them, Shiva hesitates to take the relationship further due to his bitter breakup with Sahithya (Madonna Sebastian).

The film was initially scheduled for release in February 2026; it eventually released on 26 June 2026. Abhinav Subramanian of The Times of India wrote, "Romances built on amnesia tend to mistake noise for feeling, piling on contrivance until it all rings false. Heartin keeps the heat low, and a premise you have seen many times over goes down easier than it should". Akshay Kumar of Cinema Express wrote, "Heartin has the ingredients of an engaging romantic drama: An old flame, a new love, and an accident-induced memory loss. But debutant Kishore Kumar never breathes enough life into its people for their joys or heartbreaks to matter".
