채창현

Chae Chang Hyun is a South Korean singer, dancer and former member of TREI. Before debuting, he spent nearly 10 years as a trainee at different agencies.

Originally a duo alongside Lee Jae Jun, he debuted in 2017 as TREI's main rapper and maknae with their digital single "Up". The agency, Banana Culture Entertainment, decided to restructure the group and added a third member in 2018 and re-debuted as a trio in 2019 with their first mini-album, "Born". Unfortunately, the group was not successful and disbanded in mid-2020.

He appears to be out of the entertainment industry.
