ooo this is a good question! Aching Joints is the one fic where the title isn’t connected to a song/poem, so that’s part of it! it’s also rlly integral to the story itself… but I’m not gonna lie, in all my master files it’s written in lowercase letters 🥲 the decision to capitalize was right at the last second, maybe because it felt like such a big thing to publish multi-chaptered fic like that? hehe thanks for asking 💖💖
