I've been lurking, but had to delurk to just say something today, about what's bothering me about some of these comments about Liu Wen, and her experience with men, since she's a super model, and she lives in NYC etc etc. People who bring this up, usually use it as evidence that Liu Wen can't possibly be showing her real self in this show, since she can't be this shy and this uncomfortable around Siwon. Then there are those who say that she's grown up as a conservative small-town Chinese girl, and that she's truly is completely uncomfortable around Siwon's overt and possibly too fast overtures for skinship, and for emotional vulnerability.
IMO, the reality is probably a combination of both, and if you watch that recently released Elle video, you'll see both sides of Liu Wen appearing.
There are two kinds of naked - emotional and physical. As a model, Liu Wen's job requires physical nakedness. In the fashion industry, the standard of nakedness is MUCH more casual than outside the industry. Catwalk models need to change outfits so quickly that they regularly strip back stage, before reaching the changing area. There's no time for modesty, not if you want to meet professional standards for speed. Also, there are people who need to access your body, for makeup, for hair, for body makeup, for clothes adjustment etc etc. There is no way you can say no to such things, and everyone needs access to her body to be able to do their jobs. On the other hand, emotional nakedness requires a willing vulnerability, and a trust, that the other person who sees you naked emotionally will not laugh, point fingers, or make a joke of you. Granted, when one is physically naked, one is also often emotionally vulnerable. However, it is possible to divorce the two, or at least to think at a meta-level and to put aside emotional vulnerability to be professional. I don't believe you can survive as a catwalk model otherwise.
So, to the video. During the dance, it is so clear to me that Liu Wen cannot force her body to be comfortable around Siwon. Poor Siwon feels it and cannot understand her physical NO, to him, other than to interpret is as a rejection. It wasn't nice of him to keep pointing it out, I think, but he also balanced that with repeated comforting and assurance (It's ok, I like you, it's ok), so he's forgiven.
To me, it's amazing that Liu Wen could not force her body to behave. She is an accomplished model. She has this ability to just know what the camera and the director wants, and she can deliver it. So what made it so hard? Her mind of course. As Siwon said, there is no switch for emotions (he said love, but I am paraphrasing). Siwon kept asking her to be emotionally vulnerable to him, even when she couldn't trust him. Of course, she's going to resist that emotional stripping. Siwon was an a$$ in that regard, sorry Siwon fans. (Full disclosure - I think SuperJunior is adorable, I'm a fan, but that doesn't mean I don't see their flaws). Wooing a woman takes time, and "in a hurry because of a lack of filming time" isn't an excuse for me. I think the next step for him is to take his own advice and RELAX. She'll come to him in her own time. I do understand his other assertion though, that he didn't want to be doing this show in a way that would force an unwilling woman to spend time with him even though she isn't interested.
Nevertheless, after their heart-to-heart talk, which I've come to believe was pretty honest (I'll tell you in a while, why I think so), they both came to an understanding. He, that she cannot be so easily emotionally vulnerable, and she, that he quickly trusts. He does seem to be more physically and emotionally open. In SJ, I'll share with you, he's the skinship prince (there's one that's worse). Needy and unashamed about it!
After their understanding, you can see in the video that Liu Wen found it easier to do both - be emotionally vulnerable and be physically seductive with SiWon. In that video you can see Liu Wen pre-talk and post-talk, and if you compare that with the earlier couple photoshoot, it's even more obvious how far they've come in understanding each other. Good for her, I say. Good for Siwon, I say, because he's learned to give her some measure of security.
So, in summary, there is no reason to bash Liu Wen. I really don't think she's lying or pretending to be shy when she isn't, or should be experienced. She IS experienced in being a super model, but I think emotionally, she's still very much a small town girl.
And oh, yes, the heart-to-heart talk. No one else was in the room. I know you might find that hard to believe, because there were four camera angles, and some competent switching of scenes, but if you look at the wide view of the room, you can see three cameras mounted on the makeup table in front of them. (they are the tube-shaped black things). One on Siwon for his close up shots, one for Liu Wen for her close up shots, one to encompass the two of them on the sofa, and the final camera mounted on a wall or a stand, higher up, to encompass the whole room. So basically, after Siwon came in for a talk, you can see there's a cut, and then Liu Wen says, seemingly out of nowhere, "now, ok, sit?" That's after they set up the cameras, cleared the room and gave them the go ahead. Then in post-production, the editor simply uses the footage from 4 cameras, and cuts them together for the audience to follow the conversation, just as if you were in a drama.
