Lee Jung Hoon is a South Korean singer, dancer, and former member of TST (일급비밀; previously known as TOP SECRET). He graduated from Global Cyber University with a bachelor's degree in Broadcasting Entertainment.

He made his debut in January 2017 as TOP SECRET's rapper with their first mini album, "Time's Up". The group changed their name the following year to TST but faced controversy with Kyeong Ha's legal charges later that same year. They were never able to gain a steady fanbase and presumably disbanded due to inactivity in early 2020.

As no formal announcement of the group's disbandment was ever made, he decided to announce his official departure from the group in October 2020 to open a YouTube channel with his girlfriend. He has not been active on TV ever since.
