Castro told American Songwriter
that she started writing "Wrong Places" after moving to Los Angeles to escape a breakup. After about five months, Castro started developing a "love-hate relationship" with the city. She loved being surrounded by creative people, but hated the sense of loneliness she felt there.
Castro started thinking about the line, "Looking for love in all the wrong places." She was going out with friends and having fun, but wasn't meeting anyone she could form a romantic attachment with. "I remember waking up each morning thinking that I was trying to find love but that setting just wasn't where I was going to find it," she explained. "I was in a vulnerable state and I was lonely. That's where 'Wrong Places' came from, writing down all those things I was feeling."
