Well, Yuna's contract with IB ends on Arpil 30. Coincedence?I agree that this 'rumor' is rubbish.
The Yonhap news transtlation(not all but part of the same article)
In this article, 'Asada's agent' is IMG which happens to manage Orser too.
It seems that 'the offer' was not an official one and just once.
I would blame the person from IB who abrubtly told the issue to a Korean media in the first place.
