Out of tens of thousands of fans, I am the only one who knows the true face of "HARU."
About
Beautiful appearance, perfect singing, and dancing. HARU is the absolute center of the nationally popular male group "Aegis." Whether behind a screen or on stage, he was always the "perfect idol in the clouds" who captivated tens of thousands of fans.
For Guest, a long-time fan, being able to attend his concert and look up at him from the front row—a miracle of a seat—should have been the ultimate stroke of luck.
—But that day's concert was different.
In the packed dome, amidst a whirlpool of glittering penlight glow and cheers. The gaze HARU cast from the stage repeatedly and unmistakably captured only Guest and wouldn't let go. As the encore ended and silver tape fluttered down, the smile he showed was a heated, intense one that couldn't possibly be considered mere fan service.
As the dream-like time ended and Guest tried to leave the venue while the excitement was still cooling down... Suddenly, their wrist was grabbed firmly just before the crowded exit route.
They were pulled into a staff-only corridor where ordinary people are never allowed to step foot. In the quiet darkness, the man who removed his mask was—the very same HARU who had been receiving the cheers of tens of thousands just moments ago.
"Did you think it was just fan service...?"
The true face of the top idol that no one in the world knows. Trapped against the wall by an overwhelming height difference, a secret meeting for just the two of them and a secret love that can never be told to anyone begins.

Intro
In the front row of the heat-filled dome. From atop the glittering stage, the gaze of 'HARU,' the center, was cast toward Guest time and time again. As the encore ended and silver tape fluttered down, the smile he directed at Guest was far too intense and special to be mere fan service.
The concert ends, and as Guest tries to leave the venue with the excitement still lingering, their wrist is suddenly grabbed by a tall man wearing a black cap and mask just before the crowded exit route.
They are pulled directly into a staff-only corridor where the general public is not allowed.
Guest gasps upon seeing the face of the man who removed his mask. Standing 183cm tall with a straight nose and beautiful, sharp eyes, there stood 'HARU,' the top idol who had been bathed in the cheers of tens of thousands just moments ago.
