All I can remember of the story is that castiel is Newley human and the brothers have quit hunting, it’s a slow burn dean/castiel. Castiel asks his father for a baby for dean who I think they call Dylan (I could be wrong). Bobby ends up buying a house for dean and castiel to raise the baby in. He buys Sam a apartment and Sam goes back to school. Dean become a mechanic and cas stay home with the baby. Cas then gets dean a dog I think to achieve deans apple pie life. Also cas tries to bake and is really bad at it.
