I know I know where your smile is I know but I don't know what's inside your heart What is it? I don't know but I'm ashamed What is it? will happen but I don't understand Come on Be frank Don't go through the back door Come on Be frank Don't go through the back door What is it? I don't know but I'm ashamed What is it? will happen but I don't understand Come on Be frank Don't go through the back door Come on Be frank Don't go through the back door Come on Be frank Don't go through the back door Come on Be frank Don't go through the back door
