Yes Jiwoo really needed help for the "snowy slope" while wearing high heels.It was different situation when she was in another pair of hight heels with tighter strings. If she could not get support , she would slip down definitely. As a gentleman, YJ would offer help at any time, whether he was Min Heong/Chun sang or not. so it was not acting or performing. WS fans would not hate JW on this. Jealous of course, many YJ fans wished to replace themselves as Yujin on stage, and the writer of this article was merely joking. For me, I'd like very much Yujin and Junsang together...the introduction decribes the sad feeligns for both of them .... Yujin was writing diary-letter every day to Junsang but cannot reach him of course; while Junsang was listening to music (familiar to Junsang and Yujin) and looking at the polaris every night to think of Yujin. Very sad and touching love story and keep on waiting for new episodes every week from now !!
