1 - The First Second

LUMEN Academy is a prestigious, private school designed specifically for idols who debuted before receiving their high school diploma. Hidden in the hills outside Seoul, it offers flexible scheduling, one-on-one tutoring, and high-level arts programs tailored to match the demanding lives of rising stars. Students split their time between music rooms, dance studios, academic halls, and soundproof dormitories where privacy is paramount.

From chart-topping singers to viral dancers, LUMEN is where the industry's youngest idols come to balance fame with a future-and where rivalries, friendships, and first loves bloom away from the cameras. Though the school keeps a polished image, its halls hold secrets only idols would understand.
