This week Kevin tells you what it's like to debut in a K-pop group. It's an amazing thing because you spend years training, competing against other trainees, and you never know when you'll get kicked out of the company. You sort of do auditions every weekend. Kevin was also the only trainee from overseas so he had to learn the Korean culture too. It's hard (but really rewarding when you debut). What makes a good rookie group? Always be polite to your seniors, greet them whenever you see them. Every group has their own signature greeting.
