I Helped the Female Protagonist Torture the Male Protagonist, but the Situation Turned Upside Down.

Entering a torture novel to be a female supporting character, I bind the [Harvesting the Heroine's Halo] system and help the heroine torture the male protagonist so that I can copy her golden finger. As a result, the male protagonist was also bound to the [anti-abuse system], and the more he was abused, the more he rebelled. I personally raised the boss to be the ultimate monster. After seeing through everything, he smiled sickly at me: "Have you had enough? It's my turn."
