More things have happened since we first touched on the subject:
The YNot?/CN Blue plagiarism issue over 파랑새/외톨이야 has escalated during the week as it was announced that YNot? vocalist Ju Mong – who has written 파랑새 – will take legal actions against the songwriters of 외톨이야: Ynot’s Ju Mong to take legal action against CNBLUE’s composer & songwriter.
Now it has been suggested that even the title of CN Blue’s first mini album, Bluetory has been inspired by the same song (파랑새 translating to “blue bird”) as tory (tori) in Japanese could translate to “bird”: CN Blue, ‘Bluetory’ means blue bird?.
Anyone interested in discussing this in the comments?
