If you don't study hard, you'll have no choice but to work as a bully for the "vampire" boss! So he made up his mind to study hard and change his destiny! It just seems like there have been a lot of changes... Can anyone tell me why my life is in danger if I go to college well? The nightmares that keep reincarnating, the mysterious old man's prophecy, the strange fox shadow in the foggy alley, the strange purse and fortune tellers...

Ordinary life has completely collapsed, and the inexplicable memory fragments in his mind seem to have hidden secrets. He can only continue to seek a way out of death and uncover the truth behind the layers of the layout. (This article is about gradually uncovering the fog of this special world from the perspective of a completely ordinary person, so it is a bit slow to start. The early settings will not be rolled out all at once, so please don't spray it.)
