Yes, unfortunately, Hange met their end in the manga. It was a poignant moment for fans. The circumstances leading to their death were quite intense and had a significant impact on the story.
There were several theories about the reason for Emperor Jiaqing's death. According to the records of the Qing Renzong Record, Emperor Jiaqing felt the heat on his way to the summer resort. Later, he died of a sudden stroke of cardiovascular disease at the age of 61. In addition, there was a folk legend that Emperor Jiaqing was killed by lightning because there was a thunderstorm in Chengde on the day of his death. However, according to historians, Emperor Jiaqing's death was more likely due to heart failure caused by long-term labor. Because the court concealed the cause of Emperor Jiaqing's death, there were many versions of legends about his death. In summary, the specific cause of Emperor Jiaqing's death was still uncertain. It might be due to a sudden situation caused by cardiovascular disease or other factors.
I recommend 'My Wife, You Say' to you. Although this novel didn't completely meet the requirements of the title, there was a male protagonist who was also reborn. He also watched the owner of the body and the adopted son of the body die in his previous life, and then began to change his fate after rebirth. In addition, the female protagonist in the novel also had multiple identities and memories, similar to the plot in the title. I hope you like this fairy's recommendation. Muah ~đŸ˜—
