JYP Entertainment has revealed the fourth member, Jun Han, of the label's upcoming new rookie boy group, Xdinary Heroes.

In the released teaser video, Jun Han seems to be getting ready to go somewhere far away. His suitcases are stacked inside the car, and Jun Han doesn't say a word as the car door is closed by someone outside. He takes one last glance behind him, before the car engine is started. Jun Han wakes up in the middle of the night, as his car rolls inside the car wash. He takes notice of his notebook that has the words "Hyung Jun, Music Note" written on it. Suddenly, he takes a hold of one of his suitcases and begins strumming it as if it is an electric guitar. 

Jun Han then steps out of the car, tightly grasping onto his music notebook, as he shows a determined face in front of a poster on the wall that reads, "Where your sound is formed into music".

Meanwhile, Xdinary Heroes will be revealing their members one by one as they approach their official debut. So far, the group has introduced Jooyeon, O.de, Gaon and now, Jun Han.
