Hyouga-kei Idol no Manager wo Shiteimasu ga, Mou Genkai desu.

Ryutaro Inukai is a manager utterly exhausted—both mentally and physically—from handling the famous yet notoriously difficult "Ice Idol," Hyougamine Koori, a woman known for her selfish and aloof personality. He finally drafts his letter of resignation, only for Koori to suddenly announce that she intends to retire in six months to marry her fiancé. However, his relief is short-lived; for some inexplicable reason, Koori suddenly becomes gentler, and her "icy" demeanor gradually begins to melt away. As if that weren't enough, the #1 blonde idol and the serious "Class Rep" idol also start making moves on Ryutaro! What true emotions lie hidden beneath that icy, cold exterior?
