According to frontman Tyler Dennen, The Lovers/The Devil is a 2-part concept album about a Holly Ambruso. The first part, titled The Lovers, covers the first 7 tracks, while the second part, named The Devil, covers the remaining 6 tracks. It progresses around a love story between an obsessive, romantic, emotionally unstable boy and a bitter, distant and cold girl. Halfway through the album, the roles are reversed as the boy becomes cold and distant after he realizes the girl does not love him back; and the girl realizes she made a mistake and goes on to solve it. Dennen cited as an inspiration for the album the bad relationship between his parents and bad relationships he himself has gone through.
