Actor

Chae Chang-hyun

Born 1998

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.

About WatchMind AI

WatchMind AI (WatchMind) recommends movies and TV using AI-assisted algorithms — taste profiles, semantic matching, and embedding similarity process your browsing, queue saves, ratings, and engagement into personalised picks: For You rails, daily suggestions, mood feeds, and match scores. Trailers, TMDb review excerpts, and licensed where-to-watch links support each pick. We do not host or stream full films or episodes.

Browse movies, TV series, and curated feeds such as Story Hunt. Title pages include synopses, cast, where-to-watch data from TMDb, and structured data for search engines. Personalised rails and your profile use optional Google sign-in (name, email, and account ID only to identify you — see the homepage section "What we collect and why"). The catalogue remains readable without an account.
