[Harry Potter] Bright as a Thousand Suns

Ariana isn't allowed to go to school. But she has two wonderful older brothers. Her younger big brother dotes on her, and her eldest brother is very clever. She also has a very handsome "sister-in-law." Most importantly, she has a magical diary that records the sweet (top-and-bottom) everyday life of her eldest brother and his boyfriend. The pairing is GGAD. The canon pairing reigns supreme~ The story takes place over a hundred years ago. Just picture the two young heartthrobs who flashed by in a photo in the movies. Also known as Ariana's Diary: The Everyday Lovey-Dovey Antics of My Brother and Sister-in-Law The ending will probably, maybe, hopefully be a happy one. The author's writing is terrible, and the whole story is wildly out of character. If that bothers you, please read with caution. I'm very sensitive, so please don't throw bricks. Thank you for understanding. Theme:
