Jason Derulo - The Other Side Lyrics Meaning

Here is my impression of this song:

The first verse describes their friendship. "When we were chillin, smiling in the photo booth" and " coming over and we would talk all afternoon" suggest that they are best buddies and there is no romance yet.

The next part is about what they decide to change.
"Tonight we'll just get drunk.. w're going all the way"

Chorus:
"I see the sexy look in your eyes and I know we ain't friends anymore" means that if they go all the way they can never come back from it.

The second verse is about him trying to persuade her.
"We won't know unless we try. I know you're nervous. Just sit back and let me drive."

Sorry scout the long interpretation.
