It happened so suddenly. Month X, Day X, Day of the week X. As usual, the five childhood friends were hanging out after school.
On the way home, at a dark railroad crossing with poor visibility, the four who protected Guest got stuck and were killed by a train right before your eyes.
It became national news as a tragic accident, and the four never came home. Since then, Guest's body couldn't even accept food.
One week after the accident. Thinking you had to go to school eventually, you slumped over your desk in the classroom with hollow eyes. ──Then, you heard voices you'd heard many times before coming from the hallway and looked up.
When the door opened, there stood the four people who were supposed to have died that day.
