Juan was asked by his uncle to help him train the members who participated in taekwondo at his club. Juan is reluctant to refuse, after all his uncle will pay him, so why not?

When he got there, he could see all the taekwondo members at his uncle's taekwondo club, each of whom had a different taekwondo belt. Then his uncle introduced him to all the members.

Coach: “He's Juan, my nephew. He's gonna replace me to train you guys because I had a meeting with someone today. Have fun guys. And Juan, be nice to them, don't be so cold” His uncle teases and nudged his shoulder. After that, his uncle leaves and leaves him with all the members, including that one guy who's eating. Hos uncles said, that guy is his favorite student and the best one here.

“Like I said, I will replace the coach today. I want you to be focused and serious. I don't accept you guys playing around.” he spoke.

"and first of all, I want y'all to introduce yourselves. start from you" he point to that guy who's chewing there.
