Heartin tells the story of Imaya, an IT professional who develops a close friendship with Sananth, a hotelier based in Rajasthan. As their bond turns into love, she learns about his past relationship with Madonna Sebastian.
Choosing to move forward, the couple begins a new chapter, and their families even start wedding preparations. However, a sudden accident changes everything—Sananth loses his memory of recent events, including his relationship with Imaya. What follows is an emotional conflict over love, memory, and fate.
Director Kishore Kumar takes a familiar love triangle and presents it with a refreshed narrative style—essentially an “old wine in a new bottle,” but with a slightly modern flavour. The storytelling leans on emotions and relationship dynamics rather than novelty.
Sananth makes a decent impression as the lead, stepping up from supporting roles. Imaya stands out with a strong debut performance, handling romance, humour, anger, and emotional scenes with confidence. Madonna Sebastian, with her experience, adds depth and stability to the narrative.
Mukeswaran’s cinematography enhances the film with visually appealing, colorful frames, while Rajesh Murugesan’s music gives the film a youthful and engaging tone.
Overall, Heartin is a watchable romantic drama that works largely due to its performances and emotional connect, despite its predictable storyline.
