Mr. Miller's Fake Wife

My family went bankrupt, and my brother was dying. To save him, I was sold to the Miller family to marry their notorious, wheelchair-bound heir. They thought I was just a desperate, helpless bride. But on our wedding night, my 'crippled' husband stood up and pinned me by the throat. What he didn't know? I’m a top-tier hacker and asset liquidator. I secretly linked his illegal lab’s detonator to my heartbeat. Now, we are trapped in a deadly fake marriage. He wants to destroy his corrupt family; I secretly want his entire empire. In this house full of monsters, let's see who eats who first.
