《Mr》的歌詞中有if i am的歌詞，具體歌詞如下：
If I be the one to say
I'm sorry for everything
You've been through
If I be the one to say
I'll take the blame
And I'll be fine
If I be the one to say
I'll be your Mr. right
Then you'll be my Mrs. right
If I be the one to say
Let's go back to the start
Now that I know who you are
We'll never go apart
So if I be the one
To say those words
To you my dear
If I be the one
To lay my heart at your feet
Just promise me you'll be there
Cause I need you by my side
Cause I am your Mr. right
Oh yeah~ oh yeah~ oh yeah~
Just promise me you'll be my Mrs. right
