After Switching Families with My Younger Sister, I Went on a Rampage

In my previous life, my biological parents brought my younger sister back to their wealthy family.

Because she was gentle and soft-hearted, the fake heiress often joined forces with outsiders to bully and torment her.

Driven to the point of a heart condition relapse, she died on the sports field in front of everyone.

And because I had no powerful connections to back me up, I offended the wrong people.

I died an untimely death, and my parents were left to spend their twilight years in loneliness.

Reborn, my younger sister asked me, "How about we...?"

I nodded without hesitation. "Switch!"
