This is a romantic love story about the planet Argo in the year 7074 of the Gregorian calendar in the Milky Way galaxy.
Princess Charlotte, the 73rd first in line of succession of the Helhe Empire, can marry her half-brother, second in line of succession, Prince Yuriga, according to the laws of the empire.
However, Princess Charlotte was unfortunately killed in a sea of fire during an experience.
"I want to be as great an emperor as the female general, Yuriga, what about you?"
"I just want to marry you, sister."
"Ah, your desire for the throne is so persistent that it gives me a headache..."
"..."
Poor Prince Yuriga said that maybe all the conspiracy theories pointed out that he killed her, but he just really wanted to marry his sister——
Because you were buried in Beidahuang, I am going to Beidahuang to find you. I don't believe that you are dead, even if all the evidence points to the fact that you are dead. You are my forever beloved wife.
——Excerpt from "Diary of Emperor Yuriga"
