It seems you're referring to the Telugu song from the 2016 film Nannaku Prematho starring Jr. NTR and Rakul Preet Singh, composed by Devi Sri Prasad , with lyrics by Ramajogayya Sastry .

If you’d like a short analytical piece on the song, here it is: At its core, Nannaku Prematho isn’t a conventional love song—it’s a son’s raw, emotional letter to his father. The title itself translates roughly to “ With love for my father, ” setting a tone that blends tenderness with anguish.

Musically, Devi Sri Prasad moves away from upbeat dance numbers to craft a somber, orchestral melody. The piano loop that opens the track feels like raindrops on a windowpane—melancholic yet persistent. When Jr. NTR’s voice (and the vocals of in the original version) enters, the weight is immediate: the lyrics speak of broken promises, illness, and a son’s vow to restore his father’s lost dignity.
