Here are photos of Hyun Joong at the shooting site shared by fans on Twitter. Thanks to @_tomato99 for the tips!
As the shooting started, Jung Yoo Mi (Rooftop Prince in 2012 w/ Park Yoo Chun & A Thousand Days' Promise w/ Kim Rae Won in 2011 [liezle : she's quite ok here]) zipped off to Japan this morning.
Here are photos of her at the airport. Thanks to veggiedelight for sending the photos.
Tomorrow, there will be another filming on the same shooting but I read that it will be indoor.
