Reborn to Strike Back: My Brother Spoils Me Rotten

Adopted siblings who were drained of their worth and left to die by their adoptive parents and their hypocritical adoptive sister are both reborn at sixteen. The brother is reborn and quietly lays out his moves; the sister strikes back as soon as she's reborn. From testing each other to joining forces in perfect harmony, they tear apart their treacherous family, sweep through school, and conquer the business world side by side. They break free of the constraints of blood ties and fall in love. After reaching the top, they give back to society, ensuring every evildoer gets what they deserve.
