He studied at Gochang Middle School and Gimpo Jeil Technical High School, making him the only SM Artist to have studied engineering.

Jungwoo was one of the few SM trainees who joined the agency by passing the legendary "SM Weekly Audition", also known as "Saturday Audition" along side with Haechan - who also joined SM by passing "Saturday Audition". He became an official trainee of SM as of June 20 2014, but after joining, he remained the mystery trainee. He was also known as "The Mask Boy", "SMrookie #9", and "SM Ace Card". (SM is known to hide their aces/talented trainees - example: aespa's Winter).

In April 2017, he was introduced as part of SM's pre-debut training team SMROOKIES alongside with WayV's Kun and Lucas, and in the same month he was featured in Yesung's "Paper Umbrella" music video, along with Elris' Karin.

He officially debuted in 2018 as a member of NCT with the song BOSS by NCT U. In September 2018, JUNGWOO was announced to be joining NCT 127 as a new member, starting from the unit's first studio album NCT #127 Regular-Irregular.

In August 2019, he went on hiatus during Superhuman promotions because of his health issues, as he was getting too many hates from fans, he lost his confidence. For 7 months until somewhere around March 2020, SM announced he'll be back for NeoZone comeback.

Jungwoo is the lead vocalist and lead dance of NCT U and NCT 127.
