Oh~ Please calm down.
There are many hypotheses about this happening but most of what fans say are groundless.Korean fans who know inside story are actually thinking the other ways.
Let me introduce one of hypotheses.
1: Mr.Cinquanta sent each country's Skating Union a formal document
as usual. What this document is about may be "I hope outstanding skaters will participate in the 4CC, but it is not restricted."
2: The opposing part against Yuna in KSU( There are many

) and a few media hunting interesting issues are together
exaggerating the document as if Yuna skipped 4CC, It would be bad for her especially in Olympics.
3: Conclusion; Nothing changes.
Yuna has only to skate her skating in Toronto until Olympics.
This hypothesis is my allegation, not a fact but very probable.
2: I said there are a lot of anti Yuna in KSU but correctly, might be a few.
It's hypersensitive and complicated subject to say precisely. Moreover I'm not a man being able to beg the question.
