Kar tilted his head. "Coaching?"
"Yeah, so..."
"Let me explain, Sir Ishtera," a woman came behind Byul, who Kar knew to be the manager and the CEO of Byul's agency.
She started by explaining how things work. The production company usually contracted an action school for this kind of action movie; the action school would provide training, stunts, and action choreographers for the filming. For a story with esper characters, the action school had its own contracted espers as trainers for the last stage.
"Why do you need me, then?" Kar asked curiously as they entered the elevator.
"That's..." Byul scratched his neck awkwardly. "I criticized the esper and he got angry, refusing to train the actors afterward."
