[Harry Potter] A Thousand Years

Sirius's birthday fic. After Sirius dies, Harry dreams that he has gone back to Sirius's sixth year and become a transfer student at Hogwarts. No matter what he does, it's only a dream, isn't it? Pairing: Harry (Cadmus) x Sirius. Best enjoyed with the BGM "A Thousand Years." BE warning! Unrequited love! Darkening! Murderer! Death! Sirius, beware of potential triggers. If this isn't for you, don't read! (Sirius: Are you sure this is my "birthday fic"?) The ending was inspired by "Family Harmony." Thanks to Balzac, or I would have abandoned this one again.
