Hello, can you help me find a Harry Potter fanfic story, about Harry and Hermione traveling back in time. Hermione becomes/reicarnation into Sirius Black in the past, while harry potter reincarnates as Grindelwald's grandson and accidentally helps the Malfoy family's child and is adopted by the Malfoy family. Main pairing Harry/Tom Riddle and Severus/Sirius(Hermione). Thank you for your help.
