This song had been in my mind all day suddenly. How beautiful is it in your opinion?

This is a Hindi romantic song which was released back in 2007. You will find so many guys in the comment section of this song who are in their 30s and saying how they were expecting their crush will be theirs one day back when the song was released and they were in college. As you all know I got a crush on a girl in my college too who is my junior and she is 18 or 19 and I am 21 and this song is making me emotional and make me wish that one day I will be her boyfriend who will protect her from anyone.
