School Closure Cycle

The university has been closed for seven days, and we are caught up in a strange story about rules. Those who violate them will die immediately, and three people among the crowd died last night. As more and more people died, we got hints: the dead would tell lies, the memories of the dead stay on that day, and ghosts are hidden deep among us... I used the hints to catch the last ghost, and finally got on the leaving No. 17 Bus, only to find that the ghost had been beside me.
