"I'm Not Crazy" is loosely based on the hit Netflix TV show "Heartstopper", specifically aiming to portray Charlie's point of view. The song is bright and upbeat, and uses a pulsing baseline and synths to tell the story of a boy crushing on a boy, without knowing if they share the same sexuality. The song stays lighthearted until the end, where you get a bigger dive into what your mind goes through when you're constantly falling for straight men.
