Though I do not understand what the Yoochun fans are really worried about (that she will seduce him? jump on him? make babies with him? or that she will sully his pure image?), I do understand that a Korean actress doing half-naked (and entirely naked) modelling and filming puts more on the line than an actress in a culture where sex-scenes are shown on TV every night. And even though I simply couldn't care less what Korean-actor-X and Korean-actress-Y do when they're not in a drama I'm watching (well ... apart from Park Shi-hoo, probably, or Lee Jun-ki, or ... nevermind), I also, in a way, admittedly, do not want the pure images I am after spoilt by sex and sex-related and remotely-sex-related things.
That's why I'm glad that most other Korean actresses keep their bras on. Then again, I am very grateful to Jang Mi-in-ae for showing me my first Korean female breasts and butt. And very attractive samples at that. Anyway, I hope Yoochun enjoys himself with her, err, filming with her and I also hope this drama isn't as sad as it looks like it's going to be because I do like Yoochun, too.
