Choi Eun Soo is a South Korean retired singer, dancer, and former member of NPI (챌린저) and MYTEEN (마이틴) and current flight attendant. He graduated from Seoul Performing Arts High School.

He was a trainee at Campus Entertainment (캄푸스엔터테인먼트; previously known as New Planet Entertainment), and he was set to debut in September 2015 as NPI's lead rapper, lead dancer and maknae. The group released a pre-debut song, "Vampire," but then faced uncertainty as their debut date kept being delayed. In mid-2016, they quietly disbanded without having officially debuted.

After switching companies, he finally made his debut in July 2017 as MYTEEN's rapper with their first EP, "MyTeen Go!". He was originally appointed as the leader but refused the position. Unfortunately, some of the members began entering singing survival competitions like "MIXNINE" and "Produce X 101," so they could not perform with a complete lineup.
In August 2019, The Music Works (뮤직웍스) decided to disband the group. After the announcement, he chose to quit the entertainment industry. He enlisted for his mandatory military service on August 31, 2020, and was discharged in early 2022. Soon after, he decided to try one last time and participated in the show "The Idol's Band: Boy's Battle" as a keyboardist, but was not successful.

Since then, he has officially retired from the industry and in early 2024, he began working as a flight attendant for Jeju Air.
