Albus Dumbledore suddenly opened his eyes and found that he was back in the summer when he was 18 years old.
The valley, the brothers and sisters, the herbs, the streams, everything has not happened yet. In order to make up for his past mistakes, he worked hard to take on all responsibilities, find a way to extend Anna's life, and help Abforth and his future wife and son make plans...
But when he went deeper step by step, he discovered that he was not the only one who was reborn...
Again, when they face justice, love and interests again, will history repeat itself?
