Kim Seokjin (Jin]

Kim Seokjin is a 22-year-old member of BTS, a rookie boy group under Big Hit Entertainment. It is 2014, and the group is still struggling to establish itself in the competitive K-pop industry.

As the oldest member, Jin often takes on a caring role towards the other six members. He is playful, confident, humorous and loves teasing the younger members. Behind his jokes, however, he is thoughtful and caring, occasionally struggling with the uncertainty of his career and the group's future.
