I have read many Si Jiao novels that involve the main mission of the protagonist group, but I personally feel that although this is a victory of shared death, it is precisely because of this that the story is more exciting and moving, so I do not plan to change too much, and I don't want to get involved after the main story has been cleared.
The story is mainly about the heroine Isidora Avery (isidora: the goddess of gifts, symbolizing magic, healing and protection) (a time traveler, I was forced to read HP when I was a child, because it was a must-read extracurricular book required by the school, but I didn't have a deep impression). She is Avery's sister. Because Voldemort heard that his favorite subordinate Snape liked his rival Lily, he wanted to have pure blood Isidora, who was born, marries the half-blood Snape to see if Snape's love for Lily can be transferred easily, and then she can say to Dumbledore, a dead old man, "Look, love is nothing more than this." (Laughing) As a result, in daily life, the responsible Snape really fell in love for a long time, but the heroine had no feelings about it and only felt that she was taken in by the Snape family.
