The powerful new winging of the group B.O.Y KIM KOOK HEON and SONG YU VIN begins. 

B.O.Y. released their first mini album "Phase One: YOU" on various music websites at noon on January 7.

“Phase One: You” has a wide range of musical spectra of B.O.Y. with a variety of genres. The team name implies two meanings: ‘Best Of You’ and ‘Both Of You’, which is referred to as ‘KOOK HEON & YU VIN’ or ‘KOOK HEON YU VIN & Fan’.

Producer Seo Won-jin, who worked on hits such as Tenzo, Zion.T, and TAEYANG, and produced hit songs, participated, and choreographer Choi Young-joon, who had ties through Mnet’s "Produce X 101," increased the level of completion by choreographing the double title song "My Angel."

In addition, KIM KOOK HEON and SONG YU VIN wrote and composed the upbeat-tempo ballad 'Starlight', and the R&B pop 'Got Your Back' containing BOY's sweet and sensual voice, and the ballad with impressive melody and rhythm. Up to 5 lighthouses were added to the fun.

In addition, it added five more interesting songs to listen to, including KIM KOOK HEON, SONG YU VIN, Up-tempo Ballad "Starlight" with sophisticated beats written and composed, R&B pop "Got Your Back" with sweet and sensuous voices from B.O.Y., and "Lighthouse," a ballad with rich melody and rhythm.

B.O.Y. has been together for a long time, from trainee to boy group activities, to sum up. They also starred in Mnet’s "Produce X 101" last year, drawing attention from many for their unique chemistry and outstanding skills. In response, the two formed a duo and made another powerful leap forward to captivate K-pop fans.
