Tritops originally debuted in 2007 as a three-member group (Hyungmoon, Yoojoon and Ilgoon) under Joo Paramount Media with their album "Boorish Love".
After a company change to DoReMi Media, Ilgoon soon made his departure to pursue a solo career in 2009.
The group promoted shortly as a duo, but were joined by new member Woogoon in 2012 and moved to Simtong Entertainment.
After going on a hiatus as a group for three years, TriTops returned on March 29, 2012, with a new member, WooGoon, and released a single titled "I Am A Bad Guy" which featured P.O.
The MV features Ilgoon and the Japanese model Nakamine Riko as a couple.
Lee Woo-goon (이우군), Kim Il-goon (김일군), and Jang Yoo-joon (장유준) provide additional vocals.
