Creamy Mami enthralling her fans who admire her music with every concert she does throughout her career quickly gives way to encountering fanatics whose shouting during a concert nearly causes a riot in the auditorium and in the streets where it is explained that the »fanatics« are members of the Mami Fan Club. While Shingo panics as Hayato explains him the High Society Club along with its leader Shinosuke Hyoudou, Toshio fumes in frustration at Creamy Mami and Yuu falling into Shinosuke's sway so easily as he suspects that Shinosuke has ulterior motives -- a sentiment reflected in a phone call he makes that night. Shinosuke's sinister strategy is obfuscated very poorly by his enjoinder for the Fan Club to forbid cheering during the concert much to Mami's delight. Mami accidentally leaving Nega and Posi behind in the car becomes the ironic deus ex machina for ultimately learning what Toshio and Nega have been suspecting all along about Shinosuke; an abrupt bite out of crime later, Mami daydreams about whether she will encounter true love when she is older when Hayato reminds her of the concert.
