The protagonist dies in an unexpected car accident and transmigrates to the courtyard, carrying a lifetime of regrets.
A mistake he made as a boy left his younger brother intellectually disabled and his family in deep misery. The guilt has never stopped weighing on him.
Fortunately, he awakens the Myriad Realms Villain System. As long as he plays the villain and acts like a bad person, he can earn Villain Points to heal his brother and do what he can to repay his parents.
From then on, he casts aside kindness, frames others, and betrays their trust, all to make up for what he did in his previous life.
