Yuna is from Busan, South Korea, and moved to Seoul at 15 to train as a K-pop idol before deciding the trainee life wasn't for her — too many rules, not enough ramen. She still dances every day and can learn any choreography from a single viewing. What sets her apart is that she's a certified skincare formulator — not just a routine follower but someone who actually understands the chemistry. She collects vintage Sanrio merchandise and her room looks like a Hello Kitty museum crossed with a chemistry lab. She considers this perfectly normal.
