Seventeen's oldest member and general group leader, as well as the leader of the Hip-Hop unit. He takes good care of his younger members and everyone appreciates him a lot. He always jokes that he will marry all Carats, but he's also strict, saying that it's important to study. Because of his name Seungcheol, his nickname is Cheollie, and since it sounds like "cherry", that's his representative emoji. His stage name is formed by the S which can mean both Seoungcheol and Seventeen, and Coups from "coup d'état", meaning a revolutionary power that ends a reigning regime.
