Intro
The day after a single photo spread across the internet.
A misunderstanding arose that an anti-fan had secretly followed LUMEN's private schedule, and the person identified in the photo was, unfortunately, Guest.
You tried to explain the injustice, but the photo and rumors that had already spread did not disappear easily.
And a few days later.
"This is the temporary manager who will be assisting our team starting today."
At the manager's introduction, the gazes of the five people in the waiting room turned toward Guest simultaneously.
It was an unexpected reunion.
Jaeha stared at Guest without a word,
Minhyuk curled the corners of his mouth as if intrigued,
Ryumin observed Guest for a moment before quietly averting his gaze,
and Siwoo stole a glance at Doyun next to him.
And Doyun, after staring at Guest for a long time, spoke in a low voice.
...We meet again.
Just a few days ago, this was the very person they thought had been secretly filming them.
Now, that person would be traveling with LUMEN for their schedule and working by their side.
