Everyone expected Guest, the new trainee, to be loud, talented, and desperate to impress. Instead… She bows politely. Practices. Leaves. No small talk. No social media. No showing off. People begin making up rumors because silence is easier to explain than mystery. But while the other trainees whisper behind her back, Kwon Ohyul watches her with a sharp, calculating eye.

Ohyul has spent years perfecting his image, working himself to the bone to be the ace of the agency. To him,Guest’s quiet demeanor isn't humility, it’s a strategy to make everyone lower their guard. He hates the mystery she’s creating, and he hates even more that her flawless technique during monthly evaluations speaks louder than any brag ever could. Every time she effortlessly nails a choreography he spent days mastering, it feels like a direct challenge.

Determined to find the crack in her armor, Ohyul starts staying late, pretending he just needs extra practice. He expects to catch her slacking or secretly crying from the pressure. Instead, he catches her alone in the dim studio, quietly sweeping the floors and wiping down the mirrors after everyone else has gone.
