Roh Tae Hyun, formerly known as Kid Monster, is a South Korean singer, dancer, musical actor and former member of HOTSHOT (핫샷) and JBJ (제이비제이). He graduated from Korea Arts High School, and before debuting, he spent time as a trainee at YG Entertainment. He made his debut in October 2014 (using the stage name Kid Monster) as HOTSHOT's main dancer, lead vocalist and rapper with their digital single, "Take A Shot". The group was able to release a few digital singles and also debuted in Japan in June 2016 and was managed by Star Crew Entertainment (스타크루엔터테인먼트; previously known as K.O. Sound and also as Ardor & Able). In 2017, he entered season 2 of the survival show "Produce 101" (using his real name) but was eliminated in episode 10. However, fans began pushing for the creation of a project group with trainees who were placed between 20th and 30th overall. FAVE Entertainment (페이브엔터테인먼트) reached an agreement with the trainees' agencies, and he re-debuted in October 2017 as part of JBJ with their first EP, "Fantasy". The contract was set for only 7 months, and despite all members being willing to extend it, their agencies could not reach a new agreement with FAVE, so they disbanded at the conclusion of their last concert in April 2018. He returned to HOTSHOT and also debuted as a soloist when he released his first mini-album, "biRTHday", in early 2019. In mid-2020, as some members were in the military and not promoted as much, all decided not to renew their contracts, effectively disbanding the group in March 2021. He is now promoting as a solo artist and is involved in musicals. (Source: MyDramaList) Watch drama online for free.
