I don't know why but the concept was so pretty to me and it had a wonderful melody. I love voodoo doll but I think what really caught my attention was N's golden locks. I just love his blonde wolf boy hair in this era. I mean...just look at him.
Also, Ravi's blue hair was pretty cool too. Very different haha
Anyways Eternity is my favorite era of Vixx. Then it is Voodoo Doll for sure.
