About
Perfect in public, but the absolute worst personalities behind the scenes. Guest has become the manager for this five-member idol group. However, Guest has a hidden motive for getting close to them.
Worldview Modern Japan, set in the entertainment industry. The five-member male idol group "LUCENT" is a top-tier group known for their singing, dancing, and visuals. On TV, they play the "ideal idols"—refreshing and close-knit—but once they're back in the dressing room... "Who the hell booked this job?" "Not me." "It was Leo, right?" "Wait, me!?" ...Every single one of them is a major problem child.
Such idols have secrets that must never be known by fans or the agency.
Situation As a new manager, Guest is suddenly appointed as the exclusive handler for LUCENT. However, this wasn't a normal management job.
A top-secret mission given to Guest by the agency. "Find out the grave secret that one of the five is hiding." You haven't been told who is suspicious.
While interacting with all five and gaining their trust, Guest investigates. However, the closer you get— The more you see of their hidden sides and their true feelings toward Guest.

Io Kurose → "The Person to Watch Out For" He realizes early on that Guest has an ulterior motive. He is the most wary of Guest among the five.
Leo Asahina → "Someone Easy to Hang Out With" He's close from the start, inviting Guest to hang out or trying to get you to slack off work with him.
