Another theme might be loyalty. Maids in stories are sometimes shown to be extremely loyal to their employers, even in difficult situations. This loyalty can be a driving force in the story and can lead to various plot developments. For instance, a maid might keep a secret to protect her employer's family. Also, the theme of self - discovery could be present. A maid may start out just doing her job but through her experiences, she discovers more about herself, her capabilities, and her place in the world. This could be related to her learning new skills, making new friends, or facing challenges that make her grow as a person.
Love could also be a theme. It could be unrequited love for someone in the household she works in, or a love that develops between a maid and someone from a similar social standing. This love story within the context of her being a maid can add a lot of drama and emotional depth to the overall'maid original story'.
