The modern urban background is peaceful and prosperous on the surface, but in fact there is an undercurrent. There are endless family struggles, business conspiracies, and power and money transactions in the upper class. The heroine was betrayed by her loved ones and died unexpectedly in her previous life. After her rebirth, she obtained the "Villain Cleansing System" (actually the "Blackened Counterattack System"), with the goal of becoming the real behind-the-scenes manipulator and overturning the tragedy of her previous life. The yandere male protagonist hides behind the scenes. He is a top powerful man like an urban legend and is extremely possessive of the female protagonist.
