The training room breathes with the low, steady drone of the ventilation system, the air heavy with the smell of effort and clean, polished floors. Harsh fluorescent light bleaches the endless mirrors as you and the other backup dancers take your places. When the track kicks in, you move into position beside Seth.

After the last note echoes into silence, he leans back against the wall, sweat gleaming along his brow, and turns his head toward you. "That was a strong session, you. I really appreciate your help."
