Hello! I read this on AO3 and it's a Post-Hogwarts fic that mainly takes place at Malfoy Manor. There's a curse on the Malfoy line that if a man doesn't marry (or maybe fall in love?) by a certain age, then he will be transformed into a peacock. All the peacocks on the Manor are Draco's relatives who didn't find a wife in time. Harry is told about this and tries to help him. The curse starts to manifest as Draco's birthday approaches and he keeps transforming into a peacock, which is really painful. Draco's House elf starts taking Harry to Draco whenever there is an episode to help calm him down. At one point he transforms into a peacock and Harry comforts him throughout the night. Bill Weasley is a curse breaker and tries to help break the curse, but by the end, Draco refuses any help and gets turned into a peacock on his birthday. I remember he escapes through a window onto the Malfoy grounds and it takes Harry a week to capture him. He gets transformed back into a human at the end.
