I'm not entirely sure as I haven't read it in detail. But generally, it might involve the story of an emperor, his rise to power, political intrigue, and battles perhaps.
There could be a loyal general. For example, in some stories, this general helps the emperor in battles and political maneuvers. They have a deep bond of trust and respect. The general is often highly skilled in warfare and has a strong sense of loyalty towards the emperor.
Since it's called 'emperor's domination', the emperor must be a central figure. There might also be his advisors or generals. Maybe there are some characters who oppose his rule, like rebel leaders or ambitious nobles that could also be important characters in the story.
In 'A Night with the Emperor' manhwa, the story centers around a chance meeting at night between a commoner and the emperor. This leads to a series of events involving palace politics, forbidden love, and the characters' growth. The plot is rich with emotional ups and downs and keeps readers on the edge of their seats.
