The song "Circles" by James Maslow talks about a toxic relationship where the narrator is constantly running around in circles for his partner. The partner wants him, but never truly lets him go, always keeping him scratching at the surface and never revealing what's truly behind their curtains. The narrator has been through a lot in this relationship and realizes that he doesn't need his partner anymore, but she still tries to control him. Despite this, the narrator keeps running back to her because he knows she likes it, but also acknowledges that he may just have to keep running without her. Overall, the song is about the struggle of being in a toxic relationship where one partner tries to control the other, and the difficulty of breaking free from that cycle.
