All I See Is a Stranger in You

This song is about the pain you feel when you can't help but check your ex-lover's social media after a breakup.
What you see there are smiles you never knew, and sides of them that they never showed you when you were together.
"They seem happier when they're with you than when they were with me." This is an emotional love song about that moment when you realize the pain in your heart.
