It sounds like you're looking for a of the movie Aditya Varma (the 2019 Telugu romantic horror film directed by B. V. Nandini Reddy, starring Dhruv Vikram and Banita Sandhu).

Here’s a concise, helpful review to guide viewers: In short: A visually decent but emotionally flat remake of the Tamil hit Vikram Vedha — wait, correction: Aditya Varma is actually the Telugu remake of the Malayalam blockbuster Helen (2019). Actually, let me clarify: There is confusion online. Aditya Varma (2019) is not a remake of Vikram Vedha . It's an original romantic horror story. But many viewers found it weak.
