Derailment

In the previous life, my family forced me to marry a poor and ugly hoodlum, while my sister married the current richest man. Ten years later, the hoodlum became a billionaire stock trader, and I enjoyed wealth and luxury as well. At the funeral of my parents, my sister killed herself out of jealousy after realizing that I had become rich and successful. In my reincarnation, my sister grabbed the hand of the hoodlum and was determined to marry him no matter what. But she didn't know that the real stock trader was me. Her man was a puppet that I had put in front of the public.
