Kim Seung Hun is a South Korean singer, dancer, and former member of CIX (씨아이엑스) and B.D.U (비디유). He dropped out of high school and later passed the High School Graduation Qualification Examination.

Before debuting, he spent nearly 10 years as a trainee at YG Entertainment and CUBE Entertainment. After switching agencies, he moved to C9 Entertainment (C9엔터테인먼트), and he made his debut in 2019 as CIX's main vocalist and dancer with their first EP titled "Hello Chapter 1: Hello, Stranger".

In early 2024, he entered the singing survival show "Build Up: Vocal Boy Group Survivor", eventually being part of the winning team. As a result, he signed a 2-year contract with Orca Music (오르카뮤직) and became member of the resulting project group. He re-debuted as part of B.D.U in June 2024 with their first mini-album, "Wishpool". Both agencies reached an agreement for him to promote with both groups but aside from two singles, one in 2024 and another in 2026, they did not released much material.

Then, in April 2026, C9 announced the disbandment of CIX following the expiration of the members' contracts. One day later, he released a hand-written letter announcing his retirement from the music industry.
