^I think because of this pic

Yea-........ No. I just don't see it. Their face is too different. Just because ren has shoulder length blonde hair, people start saying he looks like jia, lime, etc.

i don't think so too. /after shamelessly looking up who's lime LOL/

As in Hello Venus' Lime? Their complexion is similar, but other than that, I don't see a resemblance.
My brother thought that Lime was G-Dragon when he saw their MV for "What Are You Doing Today?" XD
