The pretty Shraddha Srinath, who had made waves as Madhavan's pair in the blockbuster Vikram Vedha, besides also starring in movies like Ivan Thanthiran, Richie and Kaatru Veliyidai, is currently playing the female lead in Thala Ajith's AK59, the remake of Pink.

She had also been a part of the thriller flick K-13 directed by debutant Barath Neelakantan, where she'll be paired with Arulnithi, and the intriguing first look posters and promotional stills had garnered curiosity over the premise of the movie.

Now, the movie has underwent a major change. Darbuka Siva, who was earlier announced as the music director of K-13 has now been replaced by Sam CS, as Darbuka has plans to direct a movie, and he hadn't started composing yet. K-13 will have two songs including a montage song, and is Sam's second movie featuring Shraddha Srinath, after Vikram Vedha.
