10 INTERVIEW We asked Seoa
Q. Where would you tell a K-POP newcomer to start?
Start with the history! Once you know the flow from Seo Taiji and Boys in 1992 to today's 5th Gen, every song is twice as fun. Check the Archive's "K-POP History" timeline first.
Q. What matters most to you as a leader?
That the members keep smiling off stage too. You can practice for the stage, but team spirit is something you have to look after every day.
Q. What does "girl crush" mean to you?
It's not about looking tough. It's trusting your own voice more than other people's eyes.
