2016–2021: Origins, debut, and dissolution

After Song Yuvin launched his solo career in May 2016, Music Works revealed plans for their inaugural boy group debut slated for 2017. <ref> Before debuting in July 2017 with the EP Myteen Go!, Myteen engaged in promotional activities including busking and a reality series. Kookheon took part in the survival program Mix Nine, advancing to the final round. The group released their second EP F;uzzle in July 2018 and made their Japanese debut with "She Bad" in October that year.

Between March and July 2019, Kookheon and Yuvin competed on Produce X 101. While Kookheon was eliminated prior to the finale, Yuvin reached the final stage but did not secure a spot in the project group X1. On August 8, Music Works announced the formation of their duet unit with a debut planned for later that month. They issued a special digital single titled "Blurry" on August 24, followed by a physical release on September 19. After Myteen's disbandment on August 21, the pair continued as a duo and hosted their first fanmeeting called "The Present" on August 31.

In November 2019, they appeared on the variety program All Together ChaChaCha and confirmed their first concert "Dear, You" scheduled for December 24–25 to showcase tracks from their forthcoming EP. Their official team name B.O.Y was unveiled on November 12. The duo made their official debut on January 7, 2020, with the EP Phase One: You, which included the self-written song "Starlight". Their debut performance was broadcast on Mnet's M! Countdown on January 2.

On September 1, 2020, B.O.Y announced their return with a second EP titled Phase Two: We, featuring the lead single "Miss You" (), released on September 15. On December 5, they achieved a victory on an episode of Immortal Songs: Singing the Legend with their rendition of BoA's "ID; Peace B", becoming only the second group from the fourth generation to win on this show.

The Music Works declared on April 30, 2021, that Yuvin's contract had expired and he would be leaving the agency, resulting in B.O.Y's formal disbandment.
