The occupations in the manga My Wife is the Demon King included but were not limited to:
1. Demon King: As one of the main characters in the story, the Demon King is one of the most powerful professions in the story. He has the power to dominate the entire kingdom.
2. Bravehearts: As one of the main forces against the Demon King, the Bravehearts are humans or demons with powerful combat abilities. They go to the Demon King's territory to challenge the Demon King and protect the people of the kingdom.
3. Maid: The maid in the story was also an important profession. She provided various services for the family members of the demon king and the protagonist, including cleaning the room, cooking, taking care of sick family members, and so on.
4. Magicians: Some of the characters in the story have the abilities of magicians. They can cast all kinds of spells to attack the demon king and resist the brave.
Other characters: In addition to the above mentioned classes, there are some characters with other special abilities such as invisibility, transformation, etc. They are also indispensable characters in the story.
I'm not sure about the exact plot as I haven't read it. But generally, it might be about a man who discovers that his ex - wife, who was submissive in their past relationship, is actually a secret boss in some context, perhaps in a business or some other area. It could involve themes of self - discovery, power dynamics, and re - evaluating past relationships.
The significance could be that these stories are a part of her personal growth. They might show how she overcame challenges in her life. For instance, if she has a story about dealing with a difficult friendship, it can reflect her ability to handle tough situations.
The obvious main characters would be the ex - wife and her billionaire ex - husband. The ex - wife is likely to be a complex character, maybe strong - willed and trying to make a new start. The billionaire ex - husband could be portrayed as powerful, perhaps a bit controlling or having a mysterious side.
There were a few novels about the secrets of his wife: My Crazy Counterattack Life, Escaping Wife, The Confusion of Thirty, Marriage Road, Wife's Secret, Middle Age: Wife's Secret, Invisible Gift, Wife's Lies, Years After Prison, and so on. I hope you like my recommendation.😗
