Away is a sad song it signifies heartbreak, the song was written to tell the listener how the artist truly feel after trusting and giving his all to a woman who don’t deserve the love, after realizing this he vows that he would have nothing to do with her never again and so he is pleading with her to leave his life cause he is tired of the pain, heartbreaks and dishonesty, he is no longer interested cause after all his heart has been played with from back to front and he feels like an empty vessel now and so he is pleading to be alone
