Error is one of my top favorites because the story is beautiful and sad at the same time. I find the choreography to be very well put with the song. Hongbin and Youngji did such a wonderful job acting in this video. I really felt the love and hurt poured out through them.
Voodoo Doll is my second favorite because I really am into the dark side of Vixx and how morbid it is. Vixx is known for creepy mv's but I think this one is at the top and that is why I like it. It's different. The choreography is amazing as well as the scenery. The costumes and make up really go well with the song. It really catches my interest.
