Thriller? Watch Me Punch Hard

Whenever I think about the day when I randomly pulled people in and forgot about the audit, my tears can't stop flowing. My name is Fanfan, a time traveler. Before time travel, I was just a student who was still in school. I traveled to this world because of an accident, but I didn't panic at all. I knew that my teacher would definitely take me back when he found out that I was missing. Sure enough, the teacher contacted me not long after and said that he would let me stay here with peace of mind and let me help the world solve a small problem before taking me back. Sure enough, it didn't take long before I was approached by something called a thriller game. At this time, I understood what the little problem the teacher was talking about was.
