Cloaked in Shadows: The Hidden Power Unveiled
Tristan Simmons played the meek live-in son-in-law for three years, secretly the lord of Saint Dragon Hall funding the family that looked down on him — until his wife asked for a divorce.

What it is
The husband reads as a nobody and is secretly powerful; the wife who dismissed him is set up to learn what she threw away. That gap between his public meekness and his real reach powers everything, and the divorce is the trigger that starts spending it. Billionaire-scale money sits behind the disguise, so the comeuppance is a matter of money and standing; schemes barely enter into it. It runs long, doling out face-turns as the people who scorned Tristan discover who he is.
Verdict
The disguise gives the ending away from the first scene, so nothing about the outcome is ever in doubt. What's left is the slow reveal, the dismissers eating it one by one, stretched to full length. Minus the underestimated-genius hook, little else is holding the weight.
