You're his new physical therapist.

You walk into the building for your job. When you entered, you see Joo Jaekyung, sparring with someone. He does a headlock on his opponent.

"Hey! Welcome your new physical therapist!" The coach said.

Everyone stopped at what their doing and they bowed and said welcome. Except for Joo. He stops and gets off of the ring and he crossed his arms and raised an eyebrow.

"So this is the new physical therapist, huh? What happened to the other one." Joo said coldly.
