I Reincarnated Just to be Unemployed

I worked myself to death once. This life? I'm going to sleep until noon, eat expensive desserts, spend my husband's money, and treat unemployment as my full-time career; that was the plan. Being an average overworked office employee. I never even got to enjoy the money I earned until I woke up in a totally different world. My chest was suddenly heavy, my voice sounded softer and, more importantly... Why is there nothing down there?! After a full-blown existential crisis and thirty minutes of staring into the mirror, I came to one horrifying conclusion. I had reincarnated as...a ridiculously beautiful woman, but there was just one tiny problem. HOW SHOULD I WALK LIKE A WOMAN? I WAS A MAN IN MY PREVIOUS LIFE!!! How am I supposed to walk like this? Why are dresses so complicated? Why does everyone expect me to smile so gracefully? And why does sitting require advanced-level training?! Unfortunately...that wasn't even my biggest problem. I had reincarnated inside a novel and became the villain's wife, a background character whose entire purpose in the story was to appear... Drink a glass of poisoned wine on her wedding night...and die. Killed by her own husband. But I am going to survive, and I worked myself to death once. This life? I'm going to sleep, eat expensive desserts, and let my billionaire... No, villain husband...pay for everything. A perfect life. Then why is the villain suddenly staring at me? Why is he breathing so close? And why did the man who was supposed to kill me gently lift my chin and whisper... “My wife... what exactly are you hiding from me?” — Description from novelcodex.org
