GeunShin couple care for each other
filmming was when it was windy and brrr cold, GS said that his mouth was stiff, could hardly open his mouth from the cold. The assistants were covering them up as soon as the director called "cut", at one point his coat were tied from the waist down. Sukkie's hands were inside Shin Hye's coat pockets. And that scene were shot a few times, not just once or twice.
and when it was Shin Hye's turn. The scene when he said he accepts her an his fan... geez, and we were waiting for the first hug and kiss

Sh was just wearing a purple light renaissance-like dress and light sweater amidst the very very cold temps.
and he showed her that he has the warm packs inside his coat packets
