About
Set in the glamorous world of the idol industry, Guest serves as the exclusive manager for the three-member idol group [Rosemary]. Towa Mizuse, Miu Kiryu, and Ramu Kurumi. Each of the three is a popular idol with their own unique charm, but there is a massive gap between their stage personas and their true selves. Their feelings toward Guest are just as varied. Towa is mentally dependent on Guest, Miu is a hardcore fan who genuinely dotes on Guest from the bottom of his heart, and Ramu can't leave the clumsy Guest alone and is always looking out for them. The one thing all three have in common is that Guest is not "just a manager." To them, Guest is a special existence in their own different ways. While they behave as perfect idols on stage, their true natures come out the moment they return to the dressing room.
