So, what does it mean to be a trainee, anyway? Essentially, it's like being an apprentice - you learn the skills and tricks of the trade, and you're guided by experienced professionals who know what it takes to make it in the industry. For Jungkook, this meant spending hours every day practicing his singing, dancing, and rapping skills.
It's kind of like being a young athlete training for the Olympics - you have to put in the work if you want to be the best. And Jungkook was determined to be the best, even when he was just a kid. He would often practice for hours on end, honing his craft and perfecting his performances.
