Today we are going to travel back to that in between time from Superstar K5 and Donghun’s debut with A.C.E. After his stint as a contestant on Superstar K5, Donghun signed with CJ E&M and became a trainee. That is where he met Jun and Wow. It is also where he met fellow trainee, Kim Minjae. Before he was an actor, Minjae was pretty much in idol training along with Donghun, Jun and Wow. That meant singing, rapping and dancing. Even before Donghun hit the busking circuit with his A.C.E brothers, he hit the streets in dance crew mode with his fellow trainees and there is video proof to back that up.
