I Like the Obsessive Idiot Male Leads (ongoing)

I thought it was just a typical villainess possession story… But what do I do if the male lead is an idiot? I had been possessed into a dark fantasy romance novel as the obvious villainess who ends up getting killed. The problem is… the male lead is my husband. The bigger problem? My husband is an idiot. And the biggest problem? He’s only pretending to be an idiot—and I have to act like I don’t know! As if it wasn’t bad enough that I got stuck in the role of the dumbest woman in the empire... Now I’m stuck in this twisted, stressful mess. Can I really survive in this novel?
