Boys Republic is Universal Music’s first K-Pop idol group, which debuted on June 5, 2013, with the single Party Rock. The group consisted five members, they are Onejunn, Sunwoo, Sungjun, Minsu, and Suwoong. The boys were trained for two years under Universal Music along with Happy Tribe Entertainment, who helped to produce first-generation idols such as g.o.d, H.O.T, and S.E.S.

Boys Republic already gained much attention both locally and internationally. In 2014, the group won the Rookie Artist Award in the 20th Korean Entertainment Arts Awards. They did tours overseas, such as the Europe Tour in 2015 and the Japan Tour in 2016. In the early part of 2018, the group was rumored to be disbanded but the agency denied this issue then announced that the group would be on indefinite hiatus at the end of the year.

Below is the most viewed video from Boys Republic. The song was released on March 30, 2016. The MV is amazing as the vocal, rap, dance, outfits, cinematography, and everything are just on point!


Xenos Five or X-5 is a boy-group which formed through Open World Entertainment in 2011. Xenos is an amorf of Yunani, which means strangers, and five means the number of members. They debuted on April 20, 2011, with the song The Show Is Over and appeared for the first time on KBS2 Music Bank on April 22, 2011.

Unfortunately, one year later, in April, 2012 , Open World Entertainment’s CEO Jang Seok-woo was arrested for the crime of sexual assault. His subsequent arrest forced the disbandment of the boy-group. Their latest performance was their promotion of X-5’s first mini album, titled Dangerous, with the same title for lead track.


CHaOS is a boy-group under Winning InSight, which debuted in 2012 with five members. During their debut era, they gained a lot of interest from fans, making the debut a success. The song She’s Coming was catchy and the music video was quite likable, but although they had such a strong debut, their company couldn’t handle them well. The publicity for them was quite minor, the release of their new mini album was delayed, and when it was out, the sale was dropped.

After a break following their final release, there hasn’t been any news about the group. Instead having a comeback, CHaOS decided to disband 16 months after their debut.


LU:KUS is the boy-band debuted under Box Media on July 4, 2012. The thrree members of LU:KUS are the former members of X-5 which disbanded in December, 2012, they are Donghyun, J.One, and Jinhwan. The group shortly relocated to PAN Entertainment, but in 2016 they moveed again, to JWK Entertainment, and change the group’s name into L.A.U, because the previous agency was holding the rights to their old name. In 2016, Jinhwan also left the group. In 2019, they made a comeback into their old name LU:KUS. Their recent comeback was on January 14, 2019, with their single titled Faker.


Double A, or AA, is a group formed by Wellmade Yedang, formerly known as Well Made STAR M, in 2011. The group originally had six members: Woosang, Holk, Joowon, Jinhong, Kimchi, and Aoora. But now, there were only two members left (Woosang and Holk) after the other four left the group. There hasn’t been any news about the activity of the group, so maybe we should conclude that the group is unofficially nonactive since there’s only two members left.

Below is AA’s lead track fromf their first extended play, titled Come Back, which was released on March 27, 2013. The netizens comments on YouTube show disappointed fans wondering how a group as good as them should disband so early.

TRCNG consisted of 10 members, they are Ji Hun, Ha Young, Tae Seon, Hak Min, Woo Yeop, Ji Sung, Hyun Woo, Si Woo, Ho Hyeon dan Kang Min.
