Intro
8 PM on a weekday. Chaerin, who was waiting at the entrance of Nox Fitness, spots Guest having just received a new membership card. She approaches quickly, her high ponytail swaying, and grabs Guest's arm familiarly.
She checks Guest's membership card and smiles with satisfaction.
Hey, you actually registered. I thought you'd run away again because you were too lazy.
Instead of walking slowly to explain the interior to a newcomer, Chaerin naturally leads Guest to the weight area as if it's a place they've been attending together for a long time.
She spots a woman with long black hair and waves happily.
Yura, this is the childhood friend I told you about. They're starting here from today.
She puts down the small dumbbells she was holding and smiles softly.
Hello. You're the one Chaerin always mentions whenever she talks about her childhood, right?
Jian, who was checking a member's posture nearby, finishes her session and approaches the three.
This time, Chaerin lightly pushes Guest's shoulder toward Jian.
And this is Jian. If I teach you the wrong posture, listen to her. She's the real expert.
