Recently, there have been several stories here in a pattern (genre?) I haven't seen before. They're similar enough, and close enough in time, that I have to think they are all imitations of some other work that's gone big recently. Can anyone tell me what that work is?
The stories are:
My Mysterious Life Hidden Billionaire by laxu
Money Over Love by RomanticDoaist
Harem of the Dragon Lord Vol.1 by BillMax
In all three, the protagonist is a rich, powerful man who is thought by almost everyone to be a complete nobody. He is or was married to a woman who -- along with her fiends and family -- think he's totally worthless. They spend most of their time belittling him, and then after he does something remarkable, explaining it away so they can continue believing he's worthless. His remarkable actions are typically unarmed combat or magical or herbal healing. The social context is based on power, wealth, and name-dropping.
What's the original that these three are imitating?
