I'm kinda getting the feeling that Ji Woong might have had (or has) feelings for Yeon Soo. To others, Yeon Soo's always been pretty cold and unapproachable; but around Choi Woong, she shows a side of herself that she doesn't show anybody else. Choi Woong thinks he's the only one who knows Yeon Soo's kindness, but I wonder if Ji Woong had also seen glimpses of those moments from a distance as an observer, and slowly fell for her too? He keeps to himself and he always seems like he's got a lot on his mind, especially since he was asked to film the documentary, so I'm really curious to know what he's thinking.
