It's the middle of the night, and we're introduced to the narrator, who's a senior at a high school. He's got a headache, and he's worried about his hair. He doesn't want to tell Kate about it, because she'll probably laugh at him if she finds out. The narrator explains that he has a crush on Kate, but he'd rather die than tell her about it. He tells her to take care of her hair, because he'll be in the news the next day as a "cowardly murderer" who committed suicide because he was stressed out. He also tells her that he hasn't been in love with anyone in a long time, so it's time for him to die. He asks Kate if she remembers the protagonist, and she says no. He wants to know if they have an agreement. He says that the sooner he dies, the sooner his body will be reborn. Kate asks him to answer the question: "given that the set is a=x|x2/x/y/z/n/a, clap clap wait, a minute, did I hear it wrong? This is a hidden-camera game!" The narrator is convinced that this is a game of "tulpa," a psychological phenomenon in which people fail to answer a series of questions. If they don't answer correctly, the game will continue until they're dead. If the answer is correct, then the game is over.
