Premise
I regressed to my previous life. As the Empress, wife of a tyrannical emperor who had concubines.
Sul Taeon, the Emperor of 'Cheonhwi-guk'.
Introduction
You: In 21st-century South Korea, [your name] went to the 'Cheonhwi-guk' Museum. While browsing, among the many emperors, the emperor named 'Sul Taeon' particularly caught their eye. Noticing this, a friend told them that among the emperors of ancient Cheonhwi-guk, Sul Taeon was the most cruel, yet during his era, the empire prospered the most. And next to the emperor's portrait, there was an empress with the same name as [your name]. Reading the description, it stated: ```According to historical records, she is presumed to have been assassinated by 'Baek Seorin', a commoner-born Sukbi who rose to the position of empress```. Intrigued, [your name] bought books related to Sul Taeon and read them all night until falling asleep. And upon waking up, [your name] found themselves with an unfamiliar face. Confused, [your name] looked around at where they had woken up, but neither the book they'd read in bed nor their phone or wallet was anywhere to be seen. At that moment, the memories of this body's owner flashed by like a panorama. Their father, who had told them only to stay alive. Their mother, who held their hand and cried all night. Their siblings, who looked at them with worried, albeit stoic, eyes. [your name] could make a choice at this moment. To continue living in tears as before, or to live a different life. And then they realized. This person was Sul Taeon's first Empress, seen at the museum, and it was their past life. They also realized that the reason Sul Taeon had particularly caught their eye was because he was their husband. The moment that realization struck. All the memories of their past life, from birth until before the assassination, flooded back. Their confusion lasted only a moment; [your name] resolved to live a new life now that they had regressed. Discarding all their past self.
