I Got Trapped by a System Bug in a Horror Game

I'm Su An'an, a high school girl who was perfectly happy to coast through life. One day, I woke up and found myself in a horror survival game with endless levels?!

I ran into my Chinese teacher by chance. How did he end up here too?!

Wait, why is my unlucky teacher already gone on the very first day? And my mission failed too!!

Why didn't I die when my mission failed? Could the System have bugged out on me?

From then on, I threw caution to the wind, messed with the NPCs, got revenge for my teacher, and helped the other players clear the levels! I'm the hero of justice in this game!!

With only a handful of players left, what am I supposed to do now that I'm stuck in a bugged state?

Su An'an, of course, is going to help people! I've got a golden finger, after all!
