[Female publicist + heartthrob + succubus + punish crime + 1V3 + younger brother] In front of others, she is a black-hearted publicist, reviled by the whole people. She handles crisis public relations for the rich and cleanses her image.
After human beings, she is the succubus of hell, punishing sins with sins, letting the wicked suffer the consequences, and be punished forever in another world.
A rich man who abuses dogs, a billionaire who abuses children, a black-hearted kindergarten teacher who abuses children, a single pervert who abuses cats... Seems to have escaped punishment, but falls into a different world hell that she tailor-made.
Savior of the rich? Evil executioner!
