First (heehee), I remember the days when I would feel the need to defend YuNa in a highly aggressive manner...and I'm glad to see others taking on that job without the aggression.
Second, I can say that many YuNa fans as myself (OK, Yunatic

) were thrilled just to see YuNa back on the ice. I am grateful for especially her Arirang LP and I hope to see it again. However, over on the YuNa forum, there is a lot of guilt floating around as well, as many of us fans realize these are our selfish wishes. It is clearly evident that YuNa was not completely committed--mentally and emotionally--to staying in competition, and with that came concern for her. I also would not fault her for not continuing. What's there for us to fault her for? She's done more than we could have imagined, let alone asked from her. In fact, some fans question whether they want to see her in competition anymore, wondering if she is unhappy with her predicament in the context of possible obligations to her federation/country.
It heartens me when non-Yunatics acknowledge her unique circumstances because sometimes I feel others, especially her more vocal critics, forget that she is a major outlier of a top skater considering her background, history, and ongoing situation. Even I, as a Canadian-born ethnic Korean, cannot understand some of her difficulties; it seems impossible. For example, YuNa's first language and culture is Korean, so I imagine that trying to express herself on the ice to usually foreign audiences is quite different from my understanding, given that Canadian/American sensibilities seem intuitive and familiar to me. Performance involves a form of communication/expression, so this difference may play a part as to why some people say she looks either "cold" or like she is "acting." Furthermore, YuNa does not skate competitively in Korea for the most part. She is not used to "communicating" to familiar audiences in the setting of a competition, and I think this contributes to some of her competition jitters.
So, although I would also love to see her continue, I also would only want her to if she can be happy and at ease. And even still, I don't think that it should go on for too long, she has missed out on so much for figure skating, and I imagine that even when she retires, her life will not have some of the blessings of ordinariness that we take for granted.
