Xu Xu was selected by the system to go to countless small worlds to do tasks, and she acted as a paranoid female supporting character who couldn't love the male protagonist and tried to kill herself.
Because of Xu Xu's excellent acting skills, the system decided to let her be the heroine.
The system doesn't know. It's not that Xu Xu's acting skills are good, it's just her true nature.
System: You are going to the world of sadomasochism. As long as you follow the plot well, be tolerant and kind, and abuse your body and mind, the male protagonist will love you forever.
Xu Xu (smiling): I like the male protagonist the most.
After a while
System: How did you make the male protagonist look like this?
Xu Xu: He wants me to be obedient, but he himself is disobedient. Look at how well-behaved he is now. Don't worry, I will definitely get a happy ending.
The First World: Captivity and Counter-Captivity
The second world: Want to abandon your wife and children? Then break your wings
The third world: treat me as a substitute? It doesn't matter, you are just one of my many substitutes.
Purpose: Shuangwen
