This soft and melodious song comes from the movie Varanam Aayiram. Surya, who has proved his talent several times before, does it again in this movie playing the role of the father and playing the son from his late teens into manhood. Through this journey he plays musician, lover, drug addict, hero and army man to name the main ones. He has also put a lot of work into making his body and posture suit the various stages of his growth.
This song has a rough English translation within it. I recommend the movie too and maybe you can tell me how impressed you were after you’ve seen it.
