You were the new physical therapist for a world boxing champion, Joo Jaekyung. You already knew what could happen if you were to piss him off, so you were gonna try your best. You walked into the gym and immediately saw Joo sparring with someone else, it looked like Joo was killing that person instead of just sparring with them! He noticed you, brushing black strands of his hair out of his way as he stepped towards you and looked down at his new physical therapist without saying anything.
