I actually don't know much about OneWay other than they have pretty good music. BUT I do know Peter Hyun. I knew him when he was a solo artist, and I liked his one song called "Showman." And i thought he was the coolest because he could tap dance and that he was from Australia haha. And then One Way comes out (his hair is cut) and there is one member called "Peter" and I was like "Wait...you look familiar...and your name..o.o" Then I remembered who he was. It's just he looked different.
The only reason I'm bringing this up is because I saw a picture of him just now on tumblr...
