In a world where favoritism leads to ruin, Serenity transmigrates as a villainess whose internal monologue acts as a roadmap to fortune. When her family begins to hear her secret thoughts about their destined poverty and the hidden potential of the neglected son, everything changes. By following her 'predictions,' the mother becomes a commerce queen and the father hits the jackpot. Now, the once-neglected Serenity is treated as a living goddess of fortune, as the family scrambles to keep her happy and her thoughts flowing.
