On a rainy day, inside a house with the lights off and nothing but darkness, there was a young man holding a book, reading it in one of the rooms. Outside, the sound of birds chirping could be heard. This young man's name was Kim. His room was simple—just a bed and a study desk.
While reading, Kim found a book that had mysteriously fallen from the sky in the morning. Driven by curiosity, he decided to take it and read it. Returning home, his mother prepared lunch for him. His family consisted of himself, a 16-year-old boy named Kim; his 12-year-old sister, Mira; his 38-year-old father, Shang; and his 36-year-old mother, Nina.
They all sat down at the dining table, and afterward, each went to their own room. Back in his room, Kim was reading the book but found it was blank—there were no words. As he flipped through the empty pages, with the rain and thunder growing louder outside, he found two words written on the last page, along with drawings in red ink, resembling blood.
When Kim touched the page, suddenly his vision darkened, and he fainted.
