Dipak, a third-year physiology student, dies from electrocution during a thunderstorm and reincarnates as Klein Moretti, the protagonist of "Lord of the Mysteries," a web novel he had only read 30 chapters of. Dipak finds himself in Klein's body on the day Klein was supposed to commit suicide after learning about his friends' deaths. Armed with limited, fragmented memories of the novel and a unique game-like system, Dipak must navigate Klein's life, relationships, and the dangerous world of Beyonders. His memories of the novel become clearer only when triggered by relevant events. The story begins with Captain Dunn's impending arrival to inform Klein about his friends' suicides. Dipak aims to uncover the mysteries of this world, adapt to his new reality, and possibly find a way back home, all while trying to maintain his cover as Klein Moretti.
