Answer:
One of us is lying
5 teenagers, Bronwyn, Simon, Nate, Cooper, and Addy attend detention with teacher Mr Avery after he found phones on their bags, against the school policy. The students claim that the phones are not theirs and that someone prank them. An explosion comes from the parking lot and the teacher leaves to see if he can help. Simon begins a speech about the stereotypical personalities of the other four students and how he, through his app, is the omniscient narrator. He drinks water from a plastic cup and suffers a fatal allergic reaction (due to his peanut allergy). The others attempt to help but it is too late and Simon dies in the hospital.
Initially, the incident is considered an accident, but after a Tumblr post is shared, claiming that Simon's death was planned and the killer watched him die, the police begin to investigate and find an unpublished post by Simon that features the secrets of the other four students
