Villain Brother, Stop Pretending

[Cute on the outside, crazily criticizing the younger brother on the inside × forced to become vicious by the system, actually cowardly of the older sister] Su Yao transforms into a vicious female supporting character, and the system forces her to make the male protagonist hate her to the core. Looking at the beautiful young man in front of her who obediently called her "sister", Su Yao felt that this task was very simple. She poured coffee on him, and he whispered: "Sister, don't be angry." She ruined his hard work and he stayed up late to redo it: "As long as my sister likes it." She asked him to make a fool of herself in public, but he grabbed her clothes with red eyes: "Sister, I will be more obedient..." Seeing that the hatred value was not increasing, Su Yao was about to cry. Until one day, the system announced that the mission failed and punishment came. When she was about to disappear, the docile young man held her in his arms and wiped away her tears, his eyes full of madness: "Sister, can't you pretend anymore?" "Now that you've provoked me, don't even think about escaping in this life." Su Yao was shocked to realize that she thought she was raising an obedient puppy, but she didn't know that she had already been targeted by an apex predator.
