Fake Heiress Story Meets A PTSD Female Lead

Synopsis

After getting PTSD, all I wanted was to end it all. But the System yanked me straight into a love-hate romance about a real and a fake heiress. In my first life, I was the fake heiress. The whole family doted on the real heiress and treated me like I was invisible. The real heiress hurt herself and blamed it on me. My adoptive parents dumped me at a dog training camp, and my adoptive brother demanded I pay for my so-called sins with my body. In the end, I set the house on fire and killed everyone. Then I jumped into the river and ended it all myself. With the main cast wiped out and the whole world shattered, the System threw me straight into the next one. In my second life, I was the real heiress, but the whole family sided with the fake one. The fake heiress pretended to be sick to set me up. My own parents drew my blood to cure her anemia, and my own brother forced me to take sex photos so I could cover for the fake heiress's mess. Just as the fake heiress came to show off in front of me, the System warned me: [Don't do anything drastic in this world, or your real body will die permanently.] I laughed. I didn't care if what I did was drastic. I just wanted to die.
