Chunji thought himself to be lucky. He had his friends, family, and beloved TeenTop. s were special to him; he loved them like another family. On stage he becomes the charming, Power Voice, Chunji, off-stage, the loveable Chanhee. Life was good, in fact, he loved it.

Chanhee thought his life . It probably couldn't get any worse but he dealt with it as much as he could. His friends were there for him when his family wasn't. He had that special someone he admired from the background, but never really as much as made a move to try and initiate something. It was always like this. Maybe he should do something, maybe not. Maybe he should do something and turn his life around but he couldn't. Life was dull for the freshman student currently attending Hanyang University. 

Two completely different worlds, one person living in alternative time frames. What happens when the impossible happens and a switch is made? The unthinkable warps both Chanhees into each other's worlds and from that comes the price of another beginning.
