Why Do Audiences Love Mistaken Identity Tropes?

"I wore my sister’s diamond ring to survive. I never planned to steal her monster of a husband." ---- "You disgust me, Serena. Don’t think for a second this ring means I won’t ruin you." Those were the first words Julian Cross ever spoke to me. My twin sister, Serena, had it all—the glamour, the billion-dollar inheritance, and Julian, the ruthless, untouchable king of the city’s underworld. I was the hidden twin, a secret our family buried in the shadows to protect their perfect image. While she wore diamonds, I dealt cards in an underground casino just to survive. Until the night Serena vanishes, leaving behind no trace of her whereabout. With a fragile corporate empire on the verge of collapse, my family gives me a deadly ultimatum: step into Serena’s designer heels, wear her wedding ring, and fool her terrifying husband. Just until they find her. I thought the hardest part would be pretending to know a world of wealth I'd never touched. I was wrong. The hardest part is surviving Julian. He and Serena didn't just have a loveless marriage; they were locked in a venomous war. But when I don't flinch at his cruelty, when my street-smart instincts take over and I fight back instead of cowering, the cold hatred in Julian’s eyes shifts into something more dangerous. Obsession. "You used to beg for my attention, Serena. You used to cry when I ignored you." He said. "You used to bore me to death," he murmured, "Now? I can't figure you out. It's driving me insane." But in Julian's world, every lie has a price. The closer he gets, the closer he is to realizing I'm a fraud. And then, the phone rings. It’s Serena. And she wants her husband back.
