Hmmm, a little bit - the way Yuzuru is crossing his arms looks a little like a
unconscious self-comforting gesture (his hand grabbing his elbow), and crossing your arms is normally a bit of a defensive/protective body language-pose. That doesn't mean that he feels very upset or anything, just that Brian, possibly very calmly (I think so going by his open pose) might be correcting/or scolding Yuzuru for something. Unconsciously it can always feel like a type of attack to be told that you are doing something wrong, no matter how much you genuinely appreciate the honesty/help - so the feelings do not have to be very strong but one can still exhibit defensive body-language.
Maybe I'm a bit bored... I'm no expert, used to love "learning" about body-language - possibly not the best sources though - so plz do not take me seriously
