Summary	A young medical student’s life unravels after the sudden death of his mentor, Professor Kenuma, found lifeless in a gas-filled bedroom. What begins as a tragic accident soon spirals into suspicion when cryptic clues emerge: a torn journal page, a hidden pistol, and threatening letters hinting at a decades-old rivalry between Kenuma and another professor, Kasagami. As the student navigates police interrogations and public scrutiny, he uncovers unsettling ties to his own birthdate and a forbidden romance buried in the past. Torn between loyalty to Kasagami—now consumed by erratic behavior—and mounting evidence of deception, he grapples with shadows of betrayal and guilt. With each revelation, the line between ally and suspect blurs, leading him toward a truth that could shatter reputations, relationships, and his very identity. A haunting tale of academic intrigue, buried secrets, and the corrosive weight of unanswered questions.
