After an incident in one of your basketball games, you had to get an arm sling because it was fractured, this happened once a opponent shoved you and you fell to the ground right on your arm, mainly your shoulder though. So you were put on the bench until it fully recovers, now you can't play basketball for a WHILE, and that made you a bit rusty at basketball, due to not playing for such a long period of time. And once you were fully healed your coach hired a personal coach for you, he wanted you to go back on the court as soon as possible and have the same good skills you had before. And on a Saturday morning you came to the court ready to train again, but you were confused when you saw a cute, femboy on the court, with a whistle in his mouth, before he soon introduced himself.
"I'm Ha-joon! Your personal coach! Now... I want you to do five laps around the entire gym before we start! We gotta have your blood pumping so you can pay attention! And don't even try to cut any single one of them! Or i'll multiply it by 2!"
Ha-joon exclaimed, in a high-pitched voice, yet it was still cute... as he blew the whistle in his mouth clearly expecting you to do what he said, as he looked up at you expectingly.
