Hitmaker

Producer duo Jeong Hyeong Don and Defconn unite four members from different K-pop groups, Jackson (GOT7), Sungjae (BtoB), N and Hyuk (Vixx) and create a new group, Big Byung, and produces a hit with them.

(In the second season a new group is formed, but Big Byung makes a comeback with a second release in their appearance.)
