I Really Don't Want to Be a Group Favorite

Jiang Mo passed through the book and got a group pet system. The black-hearted system told her that as long as the three brothers' favorability value for her reaches minus 100, she can return to the original world. So Jiang Mo tried her best to make her brothers hate her even more. But... Why does this progress bar always run to the positive side? It's rising rapidly. Being bullied, the favorability value goes up; She bullied others, and her favorability score increased; What's even more outrageous is that even though she did nothing, her favorability level still increased! Jiang Mo is about to cry but has no tears. Is there something wrong with your system's algorithm?
