I'm not quite sure to be honest, my boyfriend shared this song with me before we started dating, and I cannot quite understand it. I've listened to it a thousand times, and it's like he's such a mystery to me. I believe it has to with hiding one's true self, him and his friends are lonely, maybe the people who had always been there for him. A girl broke his heart and tainted all his memories, and his soul. Then he begins about talking about the girl, looking back. And that he couldn't open up to her because he's never trusted anyone but his friends. I believe that's what the song is about, and hopefully I can figure out my boyfriends mind soon.
