What was the name of this doujin novel? The male lead is Voldemort. Is there a love story?

The female protagonist was dressed as an eastern immortal cultivator, so she knew a little about the HP plot. However, she did not know that she was in the HP world at first. Because of the female protagonist's immortal cultivation physique, the female protagonist did not grow old or die. Because of this reason, the female protagonist was conflicted for a long time about whether she should be with the male protagonist. After all, the male protagonist only had a long lifespan, but he could not grow old or die. It was also for this reason that the male protagonist decided to make a soul device. The male and female leads met for the first time. The male lead was 8 years old and the female lead was over 100 years old. At the age of 18, the female protagonist, out of the principle of keeping a low profile, did not use her special abilities, which led to her being kidnapped. She met the male protagonist who was also kidnapped. After the two escaped, the female protagonist adopted the male protagonist. This was how the road to raising him began. However, due to the female protagonist's carelessness, she lost the young male protagonist and the male protagonist was captured by human traffickers. In order to find the male protagonist, the female protagonist went to Hogwarts to be a professor. It was also at that time that she learned the male protagonist's full name and realized that she was in the HP world. The first half of the story was easy, but the second half was about the war. It was very bloody. In order to threaten the male protagonist, Dumbledore captured the female protagonist and killed her eldest son, who was still in her womb. The chaos during the war was perfectly reflected in the author's pen. It made me feel so sad that I wanted to cry. Originally, the HP plot was changed by the female protagonist, but because the male protagonist thought that the female protagonist was dead, everything returned to the original point. The male protagonist crazily killed people for revenge and was rebounded by Harry Potter's Guardian Charm and died. In order to save the male protagonist, the female protagonist gave up eternal life. At first, I thought it would be a tragedy, but the female protagonist's child was the highlight of the second half. She was smart and powerful, and she took revenge on Dumbledore.
