10 INTERVIEW We asked Hayul
Q. What's one thing you'd love people to know about Korean culture?
Age and honorific speech! It's tricky at first, but once you get it, K-dramas and variety shows get way more fun. It's all on the archive's "Korean Culture" page.
Q. Do you feel any pressure as the group's visual?
There was at first, but now I think of it as “a place to show what I love.”
Q. What outfit would you like to design yourself?
Stage outfits inspired by the hanbok jeogori. I'd love to dress all five of HYPERBLOOM in them.
