Lyric discussion by beautifullybroken117 

I've always thought that this song was about a man who realizes that he's in love with a girl who is like his best friend:

"The back of your eyes look like my mother, when we talk you're like my brother."

It suggests a familiarity that goes beyond just some random girl that he likes.

"700 faces, 700 places."

I see that as a reference to the fact that they've spent a lot of time together, been a lot of places, seen a lot of faces, had a lot of memories.

"Father got a best plan, saving his daughter for the best man."

He knows her life, the way her father is, that he wants the best man for her.

The line "where we gonna go from here?" also suggests that there is some kind of mutual relationship.

Basically, I would interpret it as: "You're my best friend, and I don't want to see you with anyone else, but I love you enough to let you go, what are we gonna do about it?"
