Swap the Rest of Your Life

My family's driver's son and I were born on the same day and grew up together. But he always resented the injustice of God. Why was he born on the same day and I was a rich and powerful young master? So in order to replace me, he exchanged his thirty-year lifespan with the life-changing system, exchanging the rest of our lives. But he didn't know that our company was about to go bankrupt. And my parents decided to give me to a fifty-year-old rich lady in exchange for my younger brother's tuition to study abroad. The family he worked so hard to get was actually the hell I always wanted to escape from.
