Mima Kirigoe, a member of a mildly-successful J-pop group named "CHAM!", decides to leave the group to become a full-time actress. She is joined by her long-time manager and former pop-idol Rumi Hidaka, and her agent Tadokoro. Mima's first job is a minor role in a television detective drama called "Double Bind". Some of her fans are upset by her change in career and persona from a squeaky-clean and innocent teen girl, including a terrifying-looking male stalker who goes by the alias "Me-Mania". Mima receives an anonymous fax calling her a traitor, and even a letter bomb that injures Tadokoro, Mima's agent. Following directions from a fan letter, Mima discovers a website called "Mima's Room" containing public diary entries written from her perspective, and which accurately discuss her daily life and thoughts in intimate and exacting detail. Mima confides in Rumi about the site, but is advised to ignore it.
