한 Seonghyeon

Seonghyeon (성현) is a South Korean Male Artist. He started in group CORTIS.

Spent his childhood with a younger sister, often participating in school dance clubs where his talent was first noticed by scouts. He is left-handed, a trait he shares with Martin, and was often seen practicing freestyle dance during his years as a trainee in the Big Hit basement. Like most of his Cortis bandmates, he was a "hidden" trainee whose preparation for debut was kept away from public social media channels to maintain the group's mystery. He debuted in 2025 as part of the younger line of the group, noted for his sharp dance lines and visual contribution to the group's "color" concept.
