Well, from the title 'sincerely i became a duke's maid web novel', it seems that the story is likely to revolve around a protagonist who, sincerely (maybe with genuine intentions), enters into the role of a maid in a duke's residence. This could lead to all sorts of plotlines. For example, she might face challenges in adapting to the strict rules of the duke's household. There could be rivalries among the servants, or she might find herself in the middle of some sort of drama involving the duke's family affairs. Maybe she has a secret past that she is trying to keep hidden while working there, and this secret could be a major driving force in the story.
Since I haven't read it, I can't say for sure. But I would assume the maid herself is a main character, and of course, the duke would likely be an important character as well.
I'm not sure about the exact plot details as I haven't read it fully. But generally, it might involve the story of a girl who becomes a maid in a duke's household and the various adventures, relationships, and challenges she faces there.
Well, in this light novel, the maid is surely one of the main characters. She is the one who experiences the transformation into a duke's maid and all the events that follow. The duke is a central figure as well. His personality, his decisions, and his relationship with the maid are likely to be important aspects of the story. There could be a co - worker among the maids or servants, a friend or a rival to the main maid character. And perhaps there is a character from outside the duke's household, like a merchant or a traveler, who somehow gets involved in the story and influences the events in the duke's mansion.

The maid is the central figure. The duke is a key character as well, his actions and decisions would greatly impact the maid's life. Besides, there could be a kind-hearted servant who befriends the maid, or a cruel head servant who makes her life difficult. The duke's heir, if there is one, could also be a main character, with his own ambitions and plans that might cross the maid's path.
