In third grade, Harry Potter welcomes a new Defense Against the Dark Arts teacher, Lupine, and his big cat. (Sirius's gaze) With the efforts of many people, he proved his godfather's innocence and got a godmother.
After going round and round, we finally met again.
Note: There is a golden finger, but it does not belong to the male and female protagonists, it is not a time travel, and it is not a system (it is also not a male and female protagonist). There are a lot of memories to kill
PS. Due to a major oversight, the main line has been reshaped recently. Not sure if it's completed yet, don't jump in for now, it's not a trap, it will be filled in
Purpose: Save as many people as possible
