I was the only one left in the empty dormitory during the summer vacation. When the night was as cold as water, the female ghost in red emerged from under the bed, her long black hair spread over the edge of the bed, and her blood-red eyes reflected my shock. She said this was her bed, and said that the dead bones sealed in the wall thirty years ago once rested on my current pillow. I am from a Taoist family, with six fires in my horoscope. She is a fierce ghost raised by thirty years of resentment, and she wants to see who has more arrogance. The mountain ghost gave her money in exchange for a promise, her essence and blood were pledged, and the cursed seal was used as proof. The remnant soul in the crack in the wall, the contract on the rooftop, and the crescent scar she bit on the side of my neck are all saying that this symbiosis is a calamity or fate, and it is no longer up to us to choose.
