Love Regulus Ao3 — Dear Cousin

The "Dear Cousin Love Regulus" niche is a beautifully sad, highly aesthetic corner of HP fanfiction. It's not for everyone, but if you want to see Regulus Black as a gothic romantic hero spiraling toward his death, you will find some of the most hauntingly beautiful writing on AO3 within this trope. Just mind the tags (especially "Underage" if Regulus is written as 15-16, and "Incest").

Use AO3's search with the following filters to find the best ones: "Regulus Black" + "Epistolary" + "Tragic Romance" -"Sirius Black/Remus Lupin" (unless you want that crossover). dear cousin love regulus ao3
