  About KNK 크나큰  

KNK 크나큰 is a five-member boy band under YNB Entertainment.  They're the company's first male idol group. They debuted about three years after their company sunbae girl group Bestie.

KNK is an acronym which stands for the Korean syllables Keu 크 Na 나 Keun 큰. Keunakeun 크나큰 literally means "great" or "to be great." To give the initials meaning for international fans, YNB Entertainment says that KNK stands for Kpop kNocK (케이팝 노크), which means "to knock on the door of K-pop with their music." That meaning in English is a little strange, but it does make the group easier to search for on the internet, so it can be useful for interested listeners to become real fans of KNK.


All five members of KNK were trainees of different companies before joining YNB Entertainment. Youjin trained at TS Entertainment, Seungjun trained at Big Hit Entertainment and later JYP Entertainment, Inseong trained at Big Hit Entertainment with Seungjun before moving to FNC Entertainment, Jihun trained at Nega Network, and Heejun trained at FNC Entertainment. They each had a long training period, with an average of 5 years, during which time they gained a lot of experience in a variety of areas.

As YNB Entertainment trainees, some of the members appeared in music videos of their label sunbaes, Bestie. They also performed as backup dancers for the girl group.

On December 15, 2015 a teaser video of the boys was uploaded on KNK's official YouTube channel.

On December 26, 2015, KNK performed publicly for the first time at the 2015 SBS Awards Festival (SAF) where they performed the two songs on their debut single album. YNB Entertainment label mates Noel, Bestie, and Almeng also performed at the 2015 SAF.

On December 30, 2015, the band's first reality show, "My Keunakeun Television," premiered on Naver TV Cast.

On January 8, 2016, YNB Entertainment opened their official Naver V app channel for the company's artists, including KNK.

On February 1, 2016, KNK began real-time broadcasts almost daily via Naver V app as a countdown to their upcoming debut. The boys showed their daily rehearsals and preparations, as well as their album jacket photo shoot and the filming for their first music video.

On February 26, 2016, the teaser for the music video of KNK's debut single "Knock" was released. The song was composed by production team ButterFly, led by Hwang Seongje who composed BoA's "Atlantis Princess," Lee Sooyoung's "Whistle to Me," and more, while the rap part was written by member Youjin.

The dance for "Knock" was choreographed by Prepix’s Ha Wooshin, and the music video was directed by Lee Kibaek.

On February 29, 2016, the band had their debut showcase at Ilchi Art Hall in Seoul, where they performed their songs "Knock" and "Angel Heart" as well as TVXQ's "Love in the Ice" and Kim Kwangseok's "On the Street."
