Very old clip round about their promotion time of O.
This is probably the first time seeing Yoochun is angry to a member.
He kept avoiding eye contact with jj till the end, but jj looked like trying to cool down Yoochun but he made it worse by teasing more.
Now Yoochun didn't mind JJ talking about his stare to the girls anymore (in come to play).
I think he is really matured now.
