Warning: The heroine is really evil, shady, there is a big age difference (the girl is older than the boy), the heroine is a super distant relative of Voldemort (so far away that even after Voldemort destroyed his family, I didn't even remember that this one existed)
It's a short story, well, one chapter is about 1,000 words. The update is not very stable. If there is inspiration, there will be more. If there is no inspiration, there will be no chapter. The heroine is not an LTP, and she was purely used for Harry's early days.
When five-year-old Harry thought the world was a piece of shit, Sarah appeared.
Her full name is Sarah Claire F. Riddle
"Do you love me?"
"Harry l like you"
"love?"
"Like."
