Chizh & Сo - Song about love

And my edits

*'крутой' - means cool, but if you write it with the capital letter, it may be a reference to the name of the very famous Russian compositor, one of the greatest hitmakers Igor Krutoy (Игорь Крутой).
So, here the line is a pun - you can read it as:
Smiling, you will say: "you are cool"
or
Smiling, you will say: "you are like Krutoy"
