The victorious team from Mnet's vocal-focused TV competition "Build Up: Vocal Boy Group Survival," B.D.U, has made an impressive debut with their mini album "Wishpool." The group, consisting of Bitsaeon, Seunghun, Jay Chang, and Minseo, showcased their powerful and emotional voices during the program, earning the chance to perform as a project group for two years. Their group name, B.D.U, stands for "Boys Define Universe," symbolizing the unique voices and charm of the four members that will create their own universe. The mini album includes five tracks, with the lead track "My One" having both Korean and English versions, and was composed by Pdogg, the exclusive producer for Big Hit Music. The group is set to embark on a world tour titled "Tour for Wishpool: Flash & Light" in August, covering 24 cities across the US, South America, and Europe, with additional tour dates in Asia to be announced later. Despite their set timeline as a project group, the members individually expressed their desire to stay together for as long as possible, aiming to establish a distinct team identity and continue creating music that resonates with their audience. The competition, "Build Up: Vocal Boy Group Survival," was aired from Jan. 26 to March 29.
