The only version where I've loved Rui as much as Doumyouji was in the J-drama. I thought Oguri Shun was excellent in that. And hot, though only in the second season. It's probably been one of the few times where I've found orange hair attractive.

YESS! This is the version I meant too. As much as I like Vic Zhou, he was too limp as Lei (IMHO). Oguri Shun, on the other hand, does that introvert/cool as ice/mysterious/elegant thing to perfection. And because Japanese Tsukasa was sooooo ugly I just was rooting for Oguri Shun as Rui all the way, orange hair or not.
