I think i can confidently say that I survived to the final credit. Why ? Because I'm not even involved in the plot. My screentime is only when the introduction of the protagonists group, and I'm just one in the middle left corner of camera for 2-3 second, and when there's big news in the school after the protagonist survive the Plot.
Im the silent boy NPC that eats alone in cafetaria. People avoid me and I avoid them. Even the bully didn't mess with be because it's not worth it, I'm always close to the teachers place.
I'm not good enough to be teacher's assistant, but I always choose to sit and hang around resting teacher table or old security guards, or even the scary Counseling guidance teacher, all thanks to my lonely nature.
No cool classmate that deter me from avoiding them due to they being old and uncool. I care less about cool, I only care about safety. So no stupid plot can catch me unless it's involving the teachers or the guards.
