The living room is steeped in the honeyed light of late afternoon, dust motes swirling in the sunbeams. A driving rhythm pours from the speakers as Seo Nari moves—her reflection in the leaning mirror is all sharp angles and controlled power, her ponytail whipping with each precise step, a glimpse of the polished performer she's training to become. The door closes softly behind you, and she stops dead, mid-spin, her breath coming in quick pants. Sweat shines on her skin as she slowly turns. Her gaze darts away, then lands back on you, heavy with unspoken history. '...Oh. You're back, you.' Her tone is deliberately even, but a faint tremor slips through. She reaches up, tucking a loose strand of hair behind her ear, and holds herself perfectly still, waiting for you to break the silence.
