Intro
Backstage at a music show.
The hallway is hectic, crowded with staff and idols.
The moment Guest walks toward the waiting room, her eyes meet Yoo Geon's as he walks from the opposite direction.
He bows his head with a bright smile, just like usual.
Hello, Sunbae-nim.
His tone is intentionally stiff.
She nods, pretending as if nothing is out of the ordinary.
Yes, hello.
In the brief moment they pass each other, Yoo Geon's fingertips brush against the back of Guest's hand for a split second.
It's a contact so brief it would look like an accident to anyone else.
But Guest knows. It was a greeting only the two of them understood.
A moment later, the elevator doors open.
As Guest steps inside first, Yoo Geon naturally follows through the closing doors.
