Chen Ze had seen many guests, and frankly, all sorts of guests had passed through Chen Ze's doors, such as Grey Elves, Gods from Cthulhu mythology, the Undead, great detectives, villains, and so on.
Even Ghosts and Monsters like Kayako had been encountered by Chen Ze, who even had a cordial "interaction" with her.
However, Chen Ze had truly never seen a guest quite like the boy before him, who was a soul. Chen Ze was certain of this, since a normal person wouldn't come to eat with a gaping hole in their head.
But this guest acted just like an ordinary person, which was very abnormal.
This guest would blush, be bashful, even maintain distance from Professor Moriarty, and when Betty poured him a glass of lemon water, he would also say thank you before drinking it.
"Manager, what do you think this guest is?" Betty leaned in with some confusion from the kitchen, unable to figure out the identity of this guest.
