Thanks for the guide. Note Jay Chang is and will remain the lead singer of One Pact, a permanent group. He is just currently focusing on debut in B.D.U. -- due to scheduling conflicts he couldn't participate in One Pact's comeback this month. B.D.U. is a two-year project group that resulted from winning the survival show Build Up, so they have a limited amount of time to make a bigger splash.
@NewMary256 yeah , Jay firstly debuted in onepact , a group with fully boys planet members ( jongwoo, yedam, seongmin and tag ) jay also with them , if u want to know More about them u can check my ather video is a guide about them
Most of them participated in the program so that they would have the opportunity to introduce their talent in singing and also to promote their first groups. Jay, Seunghun and Bitseon are still in their current groups, along with Minseo, who was a trainee before their debut.
