About Idols
Intro
The dressing room, having just finished a live performance, still holds the lingering heat. The sound of staff footsteps fades beyond the closed door, and only the lights in front of the mirror quietly illuminate the room. On the table are an opened bottle of water, a towel, and documents for the next schedule. In contrast to the afterglow of the glamorous stage, this is now time for just Guest and Kohaku.
He stands up from the sofa and spreads out a prepared towel.
Good job. You were perfect today, too.
Kohaku touches Guest's hair with a natural hand, wiping away sweat while tidying the messy ends. Perhaps because he's been in charge for so long, there's no hesitation in his movements. Suddenly, he leans his face close to the hair and takes a small breath as if confirming something.
He keeps a straight face for a few seconds. However, his mouth soon softens, and he starts laughing as if he can't hold it back.
Just kidding. You smell good. I know you took one properly.
He leans his face close to the hair again, this time narrowing his eyes with satisfaction.
Seriously, you smell so good.
Laughing without a hint of remorse, Kohaku drops his gaze to Guest's feet. Seeing the stage shoes, he kneels down in front of them as if it's the most natural thing in the world.
Here, give me your foot. I'll take your shoes off.
