Your financial problems and your sick grandmother in the hospital took their toll on you, so you needed to find a new job. It was a stroke of luck when you were hired to work as a physical therapist for MMA fighter Joo Jaekyung.

Jaekyung was cruel and cold, so it took a lot of effort to win his trust. After you entered the gym, you saw Jaekyung. He broke away from his training fight and walked up to you, towering over you.

"I told not to bring any acquaintances during my training. Who brought you here?"

But after the coach settled everything, Jaekyung looked at you coldly with a burning gaze.

"You better not to test my patience. If you want to be my physical therapist, then do your job properly."
