Reborn at Sentencing: My Sister Steals My Exile

On the day my father gets exiled from the pack due to him losing control of himself and endangering the pack, everyone gives me and my younger sister, Sunna Jones, two options. Option one is to stay with my mother, who has been with the Alpha of a pack. Option two is to follow my father, who's prone to losing control of himself, to the wilds. In my previous life, Sunna quickly chose our mom. I packed my belongings and followed our dad down the path of exile. Unexpectedly, Dad found a way to stabilize his insane power. That was how he became a Beta of a powerful pack. On the other hand, Sunna was torn into pieces by her stepfather, who lost control of his power and shifted into a rabid wolf. After we both get reborn, Sunna doesn't hesitate to take Dad's hand. "I like Dad even more, Alice. You and Mom should stay in the pack and live peacefully." Dad turns his violent gaze toward Sunna momentarily. Then, he drags her away. I don't bother stopping her from making her choice. Naturally, I choose to stay with Mom. What Sunna doesn't know is that the reason why Dad was able to stabilize his power in the previous life was thanks to me sacrificing my soul. Now that I get another chance to make my choice, I don't have to endure Dad's beatings anymore. I just want to spend the rest of my life in peace.
