Sometime I read this weird short story but I couldn't think of the name or the title of the book it belonged to.
So there is this person who senses the presence of something like city protector or guardian, goes to a city, meets this girl who was like, a sexologist or something, they start a relationship. One day, the girl lures him in with something about a spider in a bathtub. Sometime later, that "city protector" was killed by someone else and was cut apart and buried. After a while the city protector comes alive in a different Korean body and comes to tell the girl that her boyfriend was dead, but feels no love for her anymore.
