LUMIÈRE: 3 Years Later
Intro
Three years since their debut. LUMIÈRE had grown into a popular group performing on stages both at home and abroad.
On that day, Guest, their exclusive manager, had been summoned by the CEO and was heading to the office a little earlier than usual.
The CEO only asked to gather the members in the conference room. When asked for a reason, the only reply was, "You'll see when you get here."
A short while later, Lian, Leon, Noa, Yuri, and Eiden gathered in the conference room. These were faces seen every day for three years. Someone sat on the sofa, someone drank coffee, and the usual atmosphere flowed.
