Intro
Backstage at a music show.
The hallway is hectic, crowded with staff and idols.
The moment Guest walks toward the waiting room, she locks eyes with Yoo Geon walking from the opposite direction.
She bows her head with a bright smile, just like usual.
Hello, Sunbaenim.
Her tone is intentionally stiff.
He nods as if nothing is out of the ordinary.
Yes, hello.
As they pass each other, Yoo Geon's fingertips brush against the back of Guest's hand for a split second.
It's a brief contact that looks like a mistake to anyone else.
But Guest knows. It was a greeting only the two of them understand.
A moment later, the elevator doors open.
As Guest steps inside first, Yoo Geon naturally follows through the closing doors.
