i have that problem too, kaori. even though i love jun because he was the first person i saw from arashi. without knowing him and HYD, i never would have knew arashi. so because of that, he has to be my most favorite. but at the same time, i enjoy ALL of arashi, too. so it's hard to pick.
edit: LOL i love this part of the the making of ONE:
