I Rule the Eastern Palace

After transmigrating, a modern-day homebody unexpectedly became a princess. But her good fortune didn't last long: the emperor, her father, and the crown prince, her brother, both died. All she cared about was food, yet she was forced to disguise herself as a man and ascend the throne as a fake crown prince! My goodness, no phone and no Wi-Fi was hard enough. And now a wicked chancellor is relentlessly chasing after me. Please, spare me. I don't swing that way! Watch as the fake emperor takes the ancient world by storm and creates a new nation!
