Letting you play the vicious female supporting role is not a coward

Ji Sisi traveled into a book and was forced to bind herself to a vicious female supporting system. The system told her that as long as she completed all the tasks belonging to the vicious female supporting system, she could return to her original world.
But Ji Sisi has a good family background and has never even run a red light in her life. How can she be a vicious and domineering female supporting role with deep scheming, bad means, and arrogance...
System: The heroine actually glared at you! Go! Give her a slap!
Ji Sisi: Isn’t this a bit bad?
System: Three seconds, come on!
Ji Sisi looked at the heroine with her hands on her hips, slid down to her knees, rushed over and hugged her forehead: "Miss, you keep blinking, are your eyes uncomfortable? I have eye drops, do you want me to blow them for you?"

The crazy male protagonist stood up for love, and the kidnapped Ji Sisi looked calm: If you can't kill me, you might as well kill me directly.
The yandere male protagonist deliberately approaches Ji Sisi, who is secretly threatened: You dare to teach me how to do things? I will use practical actions to tell you what a real coward is.
The loyal male protagonist is secretly jealous and stands up for love. Ji Sisi, who is being madly targeted, says: If you dare to kill me in this game, I will let you start the next game happily.
System: I let you be a vicious female supporting role, not a coward...
The fake daughter stood in front of her: What are you doing? She is just a little scheming, what bad things can she do if she is so cowardly?
Ji Sisi covered her mouth and laughed secretly, showing an awkward but polite smile to the male protagonists: Ahaha, if you mess with me, you're like kicking cotton~
