best that i can Backstreet Boys

这时Best That I Can的一段歌词：
Some say that love isn't fair
But they don't know you and me
And when they tell me that love doesn't last alone
That's when i look at you
And it's alright just let me lead you
It's ok if you close your eyes
I'll be standing by your side
I'm gonna love you the best that i can
You're my heart and you're my best friend
And i promise til the end (yeah)
I'm gonna love you the best that i can
That i can..
从上面来看 ,应该唱的是“友爱”.
