# BDC (group)

BDC (Korean: 비디씨, acronym for Boys Da Capo) was a South Korean trio formed by Brand New Music in 2019. The triplet consist of members Kim Si-hun, Hong Seong-jun, and Yun Jung-hwan. The group debuted on October 29, 2019, with the single album Boys Da Capo.

## History
### Pre-debut

The trio represented Brand New Music as a quartet alongside Lee Eun-sang in Mnet's survival reality show Produce X 101. Following the show's finale, none of the members earned a spot in the consequent project group, X1. Kim Si-hun ranked 27th in the third elimination round overall, while Hong Seong-jun and Yun Jung-hwan placed 51st and 35th in the second elimination round, respectively.
On October 2, 2019, the trio starred their own reality show named Boys Don't Cry, which was aired on Piki Pictures for four weeks. The show displayed their preparation before debuting, where they had to decide a name for their future group and do a street performance.

### 2019–2021: Debut with Boys Da Capo and The Intersection series

On October 16, 2019, a teaser image of the trio was released, revealing "BDC" as the name of the group and their debut date. About two weeks later, on October 29, BDC released their special single album Boys Da Capo with the lead single "Remember Me", in which member Kim Si-hun participated in the choreography composition. Then, on November 24, they held their first fan meeting titled "BDC 1st FAN MEETING: REMEMBER YOU" at Yonsei University's Centennial Hall.
On September 23, 2020, BDC released their first EP The Intersection: Belief with "Shoot The Moon" serving as the lead single. Despite being the second release of the group, this EP was considered as their official debut.
On March 8, 2021, BDC released their second EP The Intersection: Discovery with "Moon Rider" serving as the lead single. On May 9, they held an online fan meeting titled "2021 BDC ONLINE FANMEETING 'al Fine'" through the video platform FC Live. On June 30, BDC released their third EP The Intersection: Contact with "Moonlight" serving as the lead single. On August 10, BDC released the special single "Moon Walker". The song, which was co-written by member Kim Sihun, was intended to be the finale or epilogue of "The Intersection" series. It was recorded at the same time as the lead single from the previous EP. On August 18, they released the single "Stop Now" which was produced by Bumkey as a part of the cyberbullying prevention campaign from the Blue Tree Foundation. On October 1, BDC released their debut Japanese single "Moon Walker" which consists of the Japanese versions of "Moon Walker" and "Moon Rider" digitally.

### 2022-present: Blue Sky, departure from Brand New Music and military service.

On June 15, 2022, BDC had their first comeback approximately after 10 months with the single album Blue Sky and its title track.
On February 15, 2023, in the first episode of the JTBC's music reality competition show Peak Time, it was revealed that BDC was one of the participants, where they went under the pseudonym Team 18:00 as it was one of the rules of the show where they had to perform under a new stage name assigned to them. On March 22, in the seventh episode of the show, BDC got eliminated on the first elimination round and their group's name was finally disclosed. The song "Thunder (Urr)", that was supposed to be performed by them on the third round of the show, was released under their actual name on the next day with other participants' songs.
On August 18, 2023, Brand New Music announced that the trio would part ways with the label after the release of the single "Rest" on August 26.
