26-year-old Onozawa Rika is an art and literature editor who works for a well-established publishing house. She is devoted to her work because she loves books, but for some reason has had no luck with the men she dates. These past few days, a suspicious-looking man wearing sunglasses and a trench coat has been appearing frequently around Rika, and persistently following her. A suspicious Rika tries to find out his identity. However, the man has an incomprehensible request, “I wish you won’t board the bus that comes after this”. At his insistence, Rika gives up taking the bus, but has a fateful encounter with a young man called Maruyama Hiroshi.
